because hillary represents status quo foreign policy and corruption and progress on domestic issues while donald trump represents regression on all fronts. he is the candidate of the i say bomb 'em all! constituency. i don't believe for a second that trump is less of a hawk.
fortress liberalism is maddening and hillary is light years behind the type of candidate i feel represents me, but she's also light years ahead of donald trump, which says a lot about donald trump.
the good news is in ten years we'll have another decade of voting constituency that overwhelming supports ideals of the sort sanders espouses and the passage of another decade of society's old guard who vehemently opposes anything resembling progress on domestic fronts and supports endless war on nations they've never heard of and people they've never met. if we ran these same candidates ten years from now bernie would win in a landslide.
