Quote from Ricter:
Well, except that the former wants to institute economic policies that will reverse the recovery and pitch the US back into recession, and the latter has policies that will advance and strengthen the recovery (think of it as regression vs. progression).
But other than that, yeah, there is no difference.
Oh, and the latter wants to scale back US involvement in Iraq, Afghanistan, and Pakistan according to an orderly policy and timetable (ignoring efficacy for the moment), while the GOP wants to... well, we dont' know, they don't have a coherent plan.
So aside from domestic and foreign policy, you're right, there is no difference.
