I wouldn't use the phrase "His entire political career", to try to prove a point. It was so short, and not that impressive.
Neither was that ex-one-term representative named Abraham Lincoln particularly distinguished in 1860. Particularly when compared to his predecessor, James Buchanan, who had 10 years of experience as a House member, 10 years as a U.S. Senator, was a minister to Russia and a minister to Britian, and was Secretary of State for four years before becoming President. Now which person made a better President?
Well then, we shouldn't even consider experience in voting for president. What were we thinking? I vote for Joe Schmoe the next time around, he works in a factory, and has never voted,even. But he seems like the best pick to me because he has no experience which is even better than we could ever dream of in a president.
Also, voting to authorize one of the nation's greatest foreign policy failures, and refusing to own up to that vote is so distinguished?
