On this issue, it's a wash. The outsourcing quote was in fact one of the things Obama said at the University of Maryland rally I went to. I suspect it's in his stump speech. It's very possible that Hillary has also said it--maybe earlier, I don't know.
Therefore there is nothing to choose between the two on this issue.
So you go to other issues, where there is a difference. Like the Iraq war.
And the likelihood of actually getting your program through Congress.
