@Sh4d0w_H34rt By US standards, they're the left. I know they're not by, say, EU standards. No argument there. But in the US, they're nearly universally described as the "left" party.
I'm also frustrated by their utter lack of getting stuff done, but they've been reasonably effective at blocking the worst GOP plans. Since Congress is completely R+D, and Trump has nearly complete support of the R, I'm going to support any D resistance, even if I'm not a huge fan of Ds.
