Coburn is also good buddies with Dick Durban. So it’s no surprise that he refused to support our troops in Iraq.
You are mischaracterizing Tom Coburn. You allege he voted against funding Iraq because he is against the troops. This is a nasty accusation and in my opinion an intentional distortion of Tom Coburn's record. I do not know why he voted against funding the war, but I am D@mned certain it had nothing to do with a refusal to support our troops.
Tom Coburn does things for reasons of principle, and if he voted against a defense appropriations bill, I am willing to accept his judgement as to the need to do so over yours. I have more confidence in Tom Coburn's ability to do the right thing than I do in anyone else sent to Washington. He has done so consistently, over and over again, and so in my mind he has a long enough record of doing the right thing so that I may regard any deviations by him as being for a good reason. (Though I might not know what it is until I dig into it deeper.)
