Voter anger at the Trump administration for breaking its core promises is handing Democrats support they haven't actually earned.

• Vance's own pollster found voters want the war ended, living costs fixed, "America first" followed through, and a change in the Israel relationship.
• Backers feel let down on MAGA priorities, ending wars, free speech, releasing the Epstein files, and pulling back from globalism.
• Democrats aren't gaining because of a popular agenda — they're just the fallback option for disappointed Republican voters.
• The frustration is bipartisan in nature: neither party is seen as trustworthy, but the incumbents are taking the blame.

Outlook: Unless the administration shows real progress on these broken promises, it risks losing more support heading into upcoming elections.
