The CES line starts in 2006 at {fact:ces_2006}, rises to a peak of {fact:ces_2016} in 2016 and falls to {fact:ces_2024} in 2024. The ANES line falls between 2008 and 2016 while the CES line rises.",
  "caption": "From 2008 to 2016 the ANES share fell by {fact:anes_chg_0816} points while the CES share rose by {fact:ces_chg_0816} points. Both are lower in 2024 than in 2008, the ANES by {fact:anes_chg_0824} points and the CES by {fact:ces_chg_0824}. The CES begins in 2006, after most of the ANES fall, so it cannot show whether the fall happened, and the scales differ, so the figure compares paths and not levels.",
