The GOP factions are like a restaurant that only has menu options like strychnine, wiper blades, shards of glass and used engine oil to choose from.
You won't vote for a party that "kills babies" but you would vote for one that gouges out cops' eyes on the Capitol steps.
She was outspoken on foreign policy, saying she was a hawk on terrorism but opposed regime change wars. I think that position has significant support on both the left and right, and I'm not sure foreign policy views are as easy to put into our normal boxes of dove versus hawk as they may have been in the past. On domestic policy, she wasn't running as a moderate or as a counter-balance to the left of the party. She supported Bernie Sanders in 2016 - someone who many viewed as the most far left candidate in history. Based her Politico page, she supported abolishing the death penalty, ending cash bail reform, raising the minimum wage, broad paid medical leave, studying reparations, free college, medicare for all, legalizing marijuana, and codifying Roe v. Wade with few limits on abortion. I also read that the NRA had given her an F rating. Whether fair or not, Democrats didn't like and/or trust her despite agreeing with most of her stated policy positions. I think many Republicans who like her mostly do because she seems to criticize Democrats and the left more often and more forcefully than she criticizes Republicans. She certainly has the right to do that, although it's a bit odd given how she positioned herself just a couple of years ago.
