I do not believe in any man, but I always vote against the left on principle, no matter what, because I lose very little in doing so. It only takes a few minutes of my time. Even if the republican candidate is a puppet, the election of that puppet forces TPTB to make a choice - it forces them to choose between slowing down their tyrannical agenda to maintain the illusion of opposition or shattering that illusion by ramming their agenda through anyway.

Either one of those results is beneficial for our side. The latter wakes sleeping people up while the former gives us more time.
