If you cannot support Hillary anymore take a look at mcmullin. Competent, constitutional, and honest.
Why a Democrat vote for a candidate with a conservative agenda?
It may surprise you but not all democrats are hyperpartisan ideologues. Some just want good government.
Partisan issues though, form a part of what constitutes "good government" to each side. You can't really separate them out, you just have to figure out if the balance of negatives outweights the balance of positives in a particular candidate.
