Do you think the US is doing the right thing by fighting the war in Afghanistan now, or should the US not be involved in Afghanistan now?
By a margin of 54 to 38% Americans believe we should not be involved now (HT to Glenn Greenwald for this poll). Consider that we have a Democratic president (the ostensible "peace" party). He has a Democratic Congress. They could have us out if they wanted to. But in fact they just are not responsive to the population.
I understand that polls show that the Republicans could re-take Congress this year. Voter apathy is considered a major reason. If you consider yourself a "peace" voter or you want public option style health care (the majority of Americans fall into these categories) you obviously wouldn't be voting for a Republican. But at this point why would you vote for a Democrat? Neither party is interested in being responsive to the majority of the public.
