Handy quick comparison of Clinton and Obama:
Read it at the Progressive Review.
I think this list is very good. However on the subject of the war on drugs and capital punishment, Obama has a distinguishably better record than Clinton. Obama supports continued drug prohibition, but has voted against stricter penalties and noted that the sentencing for possession of 15 hits of ecstacy is the same as raping a women at knife point. Clinton is likely to escalate the drug war, but Obama will at least not make it worse. He stops short of favoring an end to the death penalty, but he’s also voted for legislation to help curb the death penalty. More info on his police state related votes here.
