Honestly it has to suck being a moderate democrat, it seems you're stuck with either a milquetoast career politician who doesn't have any real policy ideas or anything besides "I'm not as bad as the other guy" (which is debatable); or you get a radical socialist who does have policy ideas, however, they'll turn the US into a third world shithole where there's more equality, in that more of us will be starving and poor, but EQUALLY starving and poor.

Also the first guy is probably going to bend over backwards to appease the second guy which means you get watered down versions of shit policies.
