    Party and place

    Across 12 policy issues in 2013 to 2021, Democrats and Republicans in the same kind of county differ by 43.1 points, and one party's members in deep-blue and deep-red counties differ by 5.6 points.

    DraftFigures and numbers may change as the analysis is rebuilt.what is still being checked

    Still open: the place gap is measured for the county only, and a version at the ZIP code level has not been built. Support by county margin is drawn for a subset of the issues, without an issue selector.

On this question, Democrats in deep-red counties are closer to Democrats in deep-blue counties than to Republicans in deep-red counties, and Republicans in deep-blue counties are closer to Republicans in deep-red counties than to Democrats in deep-blue counties. The survey records the county each respondent lives in and not who lives beside whom, so the comparison is between partisans in the same kind of county and partisans of the same party in opposite kinds of county.

    The party gap exceeds the place gap on every issue

    The chapter puts the same two comparisons on 1212 policy questionsEstimandcount of issuesWeightsnone (count)Populationthe CES policy questions used in the chapterPeriodCES survey years 2013 to 2021, each issue in the years it was askedSourceCooperative Election Study policy questions the CES asked between 2013 and 2021, on guns, immigration, abortion, marriage, health care and climate. Each is a yes-or-no question, coded so that the share compared is the share taking the side Democrats take more often, such as support for an assault weapons ban or opposition to repealing the ACA. The party gap on an issue is the difference in that share between Democrats and Republicans who live in the same kind of county, averaged over deep-red and deep-blue counties. The place gap is the difference between members of one party who live in deep-blue counties and those who live in deep-red counties, averaged over the two parties. Averaged over the issues, the party gap is 43.143.1 points (difference in the share taking the Democratic side, on a 0 to 100 scale)Estimandaverage over the issues of the party gap: Democratic minus Republican share taking the Democratic side, averaged over deep-red and deep-blue countiesInterval95% CI 41.8 to 44.5n118,638Weightsweight_cumulative (CES cumulative weight; each survey year carries the same total weight)PopulationDemocrats and Republicans (three-point party identification, leaners excluded) in counties with a two-party presidential margin of 20 points or morePeriodCES survey years 2013 to 2021, each issue in the years it was askedSourceCooperative Election Study points and the place gap is 5.65.6 points (difference in the share taking the Democratic side, on a 0 to 100 scale)Estimandaverage over the issues of the place gap: deep-blue minus deep-red county share taking the Democratic side, averaged over Democrats and RepublicansInterval95% CI 4.7 to 6.6n118,638Weightsweight_cumulative (CES cumulative weight; each survey year carries the same total weight)PopulationDemocrats and Republicans (three-point party identification, leaners excluded) in counties with a two-party presidential margin of 20 points or morePeriodCES survey years 2013 to 2021, each issue in the years it was askedSourceCooperative Election Study points.

The ratio varies by issue, from legal gay marriage at the low end to spending on a border wall at the high end. The place gap is small, and it is not zero. Its interval lies above zero on every issue.

    Note: A deep county is one where the two-party presidential margin is at or beyond the cutoff stated in the text. The share is measured on the side of each issue that Democrats take more often, which the data table names for each question.Note: The issues were asked in different survey years, listed in the data table, so the averages combine periods. The number in a tooltip is the smallest of the four party by county-type groups behind the row.Note: Ratios are computed from unrounded gaps, so a ratio can differ in its last digit from the quotient of the gaps as printed.Note: Intervals are 95% intervals from a bootstrap that resamples whole states; they are model based and ignore the design of the panel.Source: CES cumulative common content, 2013-2021; county returns for the two-party margin; weighted (weight_cumulative)

    How the two gaps are measured

    The data are CES interviews from 2013 to 2021, an online survey. Each respondent is matched to their county and to that county's two-party marginCounty two-party marginThe Democratic vote minus the Republican vote, divided by the sum of the two, so a positive value is a Democratic lead. Votes for other candidates are left out. in the most recent presidential election, counting the election of the interview year. The two gaps are computed from the Democrats and Republicans among them who live in a deep county, about 120,000118,638 respondentsEstimandcount of respondents with a county margin and a party, any issueWeightsnone (count)PopulationDemocrats and Republicans (three-point party identification, leaners excluded) in counties with a two-party presidential margin of 20 points or morePeriodCES survey years 2013 to 2021, each issue in the years it was askedSourceCooperative Election Study respondents. Democrats and Republicans are defined by the three-point party question, so independents who lean toward a party belong to neither group. Every estimate uses survey weightsSurvey weightsNumbers that scale each respondent so the sample matches the population on known traits such as age, race, education and region. A weighted average counts a respondent with a large weight for more than one with a small weight., and the intervals come from resampling whole states rather than respondents, because people in one state share a political environment. The issues were asked in different years, so the averages combine periods. The qualification that matters is in the definitions. A deep county is one at or beyond the cutoff above, and a stricter cutoff compares more extreme places and gives a larger place gap. The report also adjusts the place gaps for education, race, age, gender and state, so that the comparison is between respondents who resemble each other or live in the same state.

Each of these choices defines which respondents are compared. Under every one of them the place gap is a difference between people who live in different places. It is not an estimate of what living there does to a person, since people choose where to live. The report gives every estimate with its interval and sample size.

    Within a party, support moves with the county margin

    The deep-county comparison uses only the two ends of the range of counties. Figure 2 uses every county, grouped into seven bins by two-party margin, and follows support within each party across the bins for the issues in its panels. The two party lines stay far apart in every bin. Within each party, though, the lines are not flat. In all but one of them, the change from the most Republican bin to the most Democratic bin is toward the Democratic side of the issue, with an interval that excludes zero. The exception is Republican support for a path to legal status, where the interval includes zero.

Republicans in Democratic counties support a ban more often than Republicans in Republican counties, and the change is shallow next to the gap between the parties on the same issue. The two largest changes among all the lines are both Republican, on abortion and on legal gay marriage. These are also the issues with the largest place gaps in Figure 1, so place goes with opinion more on these questions than on the others.

    Look first at the vertical distance between the solid blue line, Democrats, and the dashed red line, Republicans, in each panel, then at how little either line climbs from left to right. The horizontal axis is the county's two-party margin, from the most Republican counties on the left to the most Democratic on the right. Each point is a bin of counties placed at its average margin, and the bands are 95% intervals. The Republican lines on abortion and legal gay marriage climb most. The repeal panel plots support for repeal, so its Democratic line is the lower one. Values in Table 4.

    Note: Counties are grouped by the Democratic minus Republican margin of the most recent presidential election; the data table names the bins. The two outer bins cover a wider range of margins than the others.Note: Intervals are 95% intervals from a bootstrap that resamples whole states; they are model based and ignore the design of the panel.Source: CES cumulative common content, 2013-2021; county returns for the two-party margin; weighted (weight_cumulative)

    The dot for independents with no lean sits farthest to the right, and the dot for Democratic leaners farthest to the left. Each dot is one party group's place gap averaged over the issues, with its 95% interval. The dashed line marks a place gap of zero. Values in Table 6.

    Note: The tooltip shows the smallest of the two county-type groups behind each average. The place gaps of Democrats and Republicans in this figure are the same as the averages in the figure on Republican and Democratic place gaps. Intervals are 95% intervals from a bootstrap that resamples whole states; they are model based and ignore the design of the panel.Source: CES cumulative common content, 2013-2021; county returns for the two-party margin; weighted (weight_cumulative)

    What the gaps measure, and what they do not

    Among Democrats and Republicans in deep counties, the share taking the Democratic side of a policy question differs more by party than by county on every issue. Within a party, that share is higher in deep-blue counties than in deep-red ones, and the place gap is larger on abortion and legal gay marriage than on any other issue. Followed across presidential cycles, with surveys back to 2006, the party gap rose on most of the issues, and where the place gap changed by more than sampling error, it fell. A check in the American National Election Studies, which record only the state, gives ratios of the same order of magnitude, with intervals too wide to say more. None of this is an estimate of what a party does to an opinion. Party identification and issue positions shape each other, and party has taken on other identities, so a Democrat and a Republican also differ in race, religion and much else [1]. Nor is the place gap an estimate of what a county does to a person. The respondents in deep-blue counties may differ from those in deep-red counties in ways that education, race, age and gender do not capture.

    What these surveys cannot tell you

    A cross-section cannot separate influence from selection. People choose where to live, and a 1984 survey in South Bend, Indiana found that people build discussion networks that match their own views, within the limits their surroundings set [2]. Mummolo and Nall ask why partisans do not sort by place more than they do [3]. Evidence on people who move can separate the two; Planned, Movers and opinion change (planned) takes it up. The county is one level of place, and a finer level, such as a neighborhood, could show larger place gaps. The ratio of the two gaps would change with a different set of issues. The policy questions end in 2021, so the chapter says nothing about later years.
