If it were any other democratic party, sure, but these people are only capable of shooting themselves in the foot and shoving said foot so far into their own mouths they stuff toenails. If anything this will give them the platform to make themselves look even more handicapped when they start stonewalling policies most Americans actually agree with (IE immigration enforcement). I don't see this as a win for the democrats or a loss for the Republicans because the only thing that changes is the democrats having a slightly louder microphone with which to express their handicapation
possibly very true
democrats have had a tough time challenging republicans the past while in rhetoric, so i'm guessing their main play will continue to just be blocking whatever they can, and historically americans don't tend to like that sort of play. like you mentioned, i think most americans tend to agree on what policy needs to change, they just disagree about what those changes should be, but in the end, republicans are still going to have much more say in how those sorts of things go. the main thing is, republicans don't get to run everything over democrats anymore. they have to make at least enough compromise to get a house majority, and that could make all the difference for democrats. as long as the senate balance stays about the same, democrats still also have a very respectable presence there too; if republicans don't have an easy 60 votes in there, that effectively means democrats can automatically kills lots of highly contentious legislation. since democrats don't control the presidency though, and they almost certainly won't have an easy 2/3 vote to override a veto, they're still playing the republicans' game
