The Democrats would have supported continued sanctions. They've only changed that now because it's a way of bashing Bush since we invaded.
Totally irrelevant. The UN imposed the sanctions, not the Dems or Reps. Do you think if Hans Blix came up empty on WMD the French, Germans, and Russians would have supported continued sanctions? Only if they could make more bling bling from Oil-for-Food than they could with direct commerce. The world leftists were screaming bloody murder about the sanctions even before the UN weapons inspectors came back in in 2002.
