2008: For which candidate for President of the United States did you vote? [see guide for wording in all years]
Asked of: Respondents who reported voting for president (asked post-election and in later years)
2008 presidential vote choice · Asked in 5 waves, 2008–2012 · 148,375 responses · weighted estimates computed from individual responses
Harmonized across years by the Cumulative CES Common Content (Kuriwaki); response options are collapsed where years differ. See docs/sources/ces.md. "Undervote" is flagged as a non-answer, not a vote choice: in 2025, a recall of the 2024 vote with no turnout question to screen out non-voters, about 28% of answers are Undervote (under 1% in 2024), so in that year it evidently includes people who did not vote.
