I don't blame Trump. He can't help himself. Who I do blame are all the insane people who back him up.
I don't support Trump but I also am not stupid enough to call his supporters insane. People support him because he isn't a typical Washington politician (which everyone is tired of) and there are millions of people who don't support Sanders super left wing stance. If you feel that way basically your only choice is to support Trump despite his downsides. Every other candadite will be more of the same BS.
