We don't have a functioning federal system. We have one group half composed of progressives and half of centrists, up against an obstructionist group of lying, moronic connivers who believe in confidence fairies, tax cuts that magically pay for themselves, self-aware uteri, and an earth that is 6,000 years old. It's not exactly a surprise that they would scuttle an inconvenient economic report.I'm not sure I believe Democrats are half progressives--maybe from a person standpoint, but the policy they have pushed/enacted has been 100% centrist. Or as Venn Diagram:
Clinton was kind of on the right wing of the Democratic party when he was first elected. Though to me, the really scary thing is that Regan was on the right wing of the Republican party when he won in 1980.
The lunatic left ("9/11 was an inside job") and the radical right are about equally bonkers, though the radical right is much larger and pretty much the center of the Republican party whereas the lunatic left is completely ignored by the Democratic party. Bat-shit insane doesn't really exist on a right left continuum but it has found a home among Republicans.
Moderates and centrists in real policy terms are the defining element of the Democratic party. Important to note for this group, though, is that the self-proclaimed variant that is found largely among the pundit class are largely idiots whose stated policy preferences are almost exactly Obama's stated positions, but who--again, because they are idiots--don't want to admit or even think that so they pretend that Obama is actually liberal and that Romney2012 is actually the same as Romney2008.
