John Kerry

I hope it's Corker. His foreign policy positions seem decent + he is conservative, but not am extreme ideologue (though I remember his very strong opposition to the auto companies bailout when he was peretty horrible), also he has a brain and is not afraid to use it. I remember him quite a few years back in a banking committee hearing, I think the issue was infrastructure, when he was asking questions from the other, more senior, senators saying that he wants to understand and learn; I liked that.
