Overview
- CNN chief data analyst Harry Enten said Tuesday that Democrats have cast about 57% of primary ballots so far across roughly 20 states, a pace observed at the midpoint of the primary calendar.
- Enten noted that the party with the primary-vote edge has gone on to gain or retain control of the House in every midterm cycle since 2006.
- Analysts caution that the pattern is correlational, the primary season is only about halfway complete, and turnout figures have measurement limits that make them an imperfect predictor of November outcomes.
- If the Democratic turnout advantage holds, campaigns could redirect money and messaging to different districts, which may change which House races are competitive in the fall.
- The comparison draws on recent cycles: Democrats had about 54% of primary votes before retaking the House in 2018 and Republicans had a 53% edge before winning in 2022, and media coverage ranges from data-focused analysis to more partisan framing of what the trend would mean for President Trump.
