It just must be Raul Grijalva (D-OfCourseHe'sBluffingAgain). As a native of the Grand Canyon State, I've always been proud of our ability to play far above our size...Barry Goldwater, Bruce Babbitt, Mo Udall, John McCain, Sandra Day O'Connor, William Rehnquist...that's a pretty good first line, and add to that Stewart Udall, John Rhodes (House GOP leader after Ford) and Carl Hayden (who established Congressional longevity records). It may not be Washington, Jefferson, and Madison, but it's not bad for a state that was born after Ronald Reagan.
I'm definitely getting the feeling that Grijalva isn't going to be up on whatever Arizona's version of Mt. Rushmore is. The guy has one move, right? Step One: Raul Grijalva threatens that he'll vote against health care reform because the bill isn't far enough to the left. Step Two: No one pays any attention. Step Three: Raul Grijalva supports the bill. Step Four: The bill moves a little bit further away from Grijalva's preferences. Step Five: Repeat.
Assuming there's enough time to do it, I fully expect him to try this maneuver a couple of times between when he votes for the Senate bill and when he votes for the reconciliation patch. I'm not certain whether he'll also threaten to barricade Pennsylvania Avenue to block the bill from getting to the White House for the presidential signing ceremony, but I won't be surprised.
Open invitation: he's welcome to a seat at my poker game whenever he wants.
