Democrat. I may not be the kind from my generation that you expect because I follow more Third Way principles. (I have a lot of nostalgia for the '90s, haha) I'm liberal on social issues but I do think that government spending needs to decrease so the national debt can be lowered.
Sadly, I think it's become clear since Hillary's loss and Trump's win that we may end up just having a very liberal Democratic Party and a very conservative Republican Party, with few options for centrists. I would back any Democrat over any Republican though, especially at this rate. If Elizabeth Warren runs for president in the next election cycle, I will work for her campaign.
