Deroy Murdock’s column today will give Obama and Biden ulcers. They, of course, have led with their chins in an attack on Palin’s bona fides as an opponent of pork-barrel spending by saying that she wasn’t really opposed to that famous “Bridge to Nowhere.” Murdock straightens out the record on that point, then goes on to hand Obama and Biden their heads.

He digs back a few years to the aftermath of Katrina when Senator Coburn tried to put through an amendment to drop non-Katrina earmarks to put more money into rebuilding projects like a ruined bridge in Louisiana. Both Obama and Biden voted against it.

I think that vote might be hard to explain.
