One the one hand: wait, by voting for the people most responsible for their failure? Well, WHAT makes sense. If the Dems had been in charge, their situation would be a lot better.
Chris Rock covered this:
If you vote against Obama because he can't get stuff done, it's kind of like saying 'This guy can't cure cancer, I'm gonna vote for cancer.'
On the other hand, studies show that economics don't correlate with support for Tr*mp, it's white Christians worried about losing their power over society. You can look it up. The whole "working class revolt" thing is popular because no one wants to face the ugly truth.
