Democrats are increasingly adopting a negative tone towards their own party in upcoming elections, shifting from bipartisan promises to vows against corruption in both parties. This shift indicates significant voter anger directed at the Democratic Party and the national political establishment. Candidates are hearing from voters expressing frustration with both political parties, as evidenced in town halls and campaign events. Analysis of campaign ads shows a substantial increase in negative mentions of the Democratic Party or both parties by Democratic candidates. Traditionally, candidates highlight bipartisan efforts, but Democrats are now embracing populist, anti-establishment rhetoric. They denounce a flawed political system and cite instances of defying their own party. This trend is reflected in ads where candidates emphasize standing up to anyone, regardless of party, if they are not focused on constituents' needs. Even the House Democratic campaign arm is running ads criticizing Washington as a mess. The number of Democratic ads using negative messaging about parties has significantly increased since 2018. Conversely, positive messaging about working with both parties has sharply declined. While some Democrats maintain an optimistic, cross-party message, many are responding to a voter sentiment that overwhelmingly distrusts both major parties.
