What has McCain done in the Senate this term?

Being bored I was using Stumbleupon to surf the web. I came across this page. During the current session of Congress McCain has missed 371 votes which comes out to 61.6% of the total votes. If he was my Senator I would not be very happy to have elected someone who cannot even bother to vote even half of the time. In case you were wondering Barack Obama missed 43.5% of the votes and Hillary Clinton missed 33.4%. Maybe we should have a rule if you are already in office and decide to run for a different office you should have to resign your current position. People like to make fun of Dennis Kucinich, who is my Congressman, but at least he only missed 9.3% of the votes. Again it would really piss me off to have my elected representative in Congress missing that many votes. If they care that little about representing me now how much are they going to care if they get elected President?
