Keep in mind that the Republican majority in the House is so slim and their party so fractured that Democrats could likely peel off just a couple of moderates and flip the House blue anytime they wanted to.
That they don't tells me we need some better Democrats because these seem to be putting fundraising over actual governance, instead of actually doing their jobs to counter Trump's efforts.
Remember, these are the same Democrats that voted with Republican hardliners last year. We need to hold them accountable for that and demand better candidates who will actually work and vote the way we want instead of just posing for the cameras and asking for money.
