" I think the best argument would be if you give an actual quote from Obama to explain his votes. Because I haven't read any. And again, he still has ignored the question."

"Us rushing headlong into a war unilaterally was a mistake and may still be a mistake...
IF it has happened, then at that point what the debate's really gonna be about is what is our long term commitment is there. How much is is it going to cost, what does it mean for us to rebuild Iraq, how do we stabilize and make sure that this country doesn't splinter into factions between the Shi'as, and the Kurds, and the Sunnis." - Barack Obama

This quote clearly explains his view. Rushing into the war was wrong. HOWEVER, once we were there, we had a responsibility to help rebuild the country, which means funding the war. So Obama was always against the war occurring, but considered it a poor choice to pull funding/pull out directly after we invaded.

After we had gave them time, Barrack supported a phase withdrawal.

This is a totally reasonable, consistent view, and personally one I agree with completely.
