Voting against the oath

Joseph,

[Regarding "The mark of Kaine? He gets 'F' on Scripture"] he also gets an "F" on the Constitution. According to The Freedom Index (a congressional scorecard based on the Constitution), Kaine only votes with the Constitution 1 percent of the time. He has the lowest score of anyone in Congress.

What kind of a loser votes nearly 100 percent of the time against the oath he took? According to the list, all representatives have voted against their oath.
