This should not be a big surprise:
WASHINGTON - Indiana Sen. Richard Lugar's voting record so far this year shows him breaking with his party more than most senators and, if the Republican keeps it up, more than in any of his 30 years in the Senate.
Lugar has sided with Republicans during party-line votes 66 percent of the time of the Senate votes cast through June. Only five other senators, all Republican, have voted with their party less often this year.

The change in Lugar's voting patterns doesn't even reflect his recent break with the administration on Iraq.
Evan Bayh, meanwhile, voted with his party 81 percent of the time. It's probably not fair to say Indiana has two Democrats in the Senate, but we're getting there.
