People will vote for her because the other options are worse
I just read a poll recently that said 85% of republicans would vote for George W. Bush as president again if they could, so that leads me to believe the kinds of republicans who voted in this poll are incapable of objective reasoning. We saw the same thing last presidential election cycle here on RIU, conservatives straight up denied the polling data before the results were in. Same thing with climate change, same thing with racism, same thing with sexism and income inequality... you guys simply don't believe these things exist because of the media you consume and political ideology. Then when the objective hand of reason comes in and proves you wrong a la Kim Davis, the Pope siding with climate change and against crony capitalism and income and wealth inequality, the expected new speaker of the house accidentally outing the republican party for politicizing the investigation into Benghazi, et al, you denounce judges on the Supreme Court as "activist" and say shit like "the Pope shouldn't talk about science" - even though he's perfectly qualified holding a degree in chemistry.
Sound familiar? You cherry pick what you want to accept and deny and discard what you don't like. None of it is objective, and that's why the republicans will lose another chance at the white house in 2016.
