Democrats are the new Republicans

The Democrats have moved to the right, and the right has moved into the nuthouse. Shouldn't there be one party that unambiguously supports cutting the military budget, a party that is straight up in favour of gun control, gay marriage, higher taxes on the rich, universal healthcare, legalizing marijuana, and steep, direct taxing of polluters? These aren't radical ideas. A majority of Americans are either already for them, or would be, if they were properly argued and defended. And what we need is an actual progressive party to represent the millions of Americans who aren't being served by the Democrats.
