It's hard to be bipartisan with catty, petty Republicans like Iowa's Charles Grassley

Obama keeps talking bipartisanship, as John notes below. But, Iowa Republican Senator Charles Grassley exposed the level of his pettiness (and bitchiness) over the weekend. He launched a catty attack on Obama via Twitter;

Republican Sen. Chuck Grassley says that President Barack Obama "got nerve" to go sightseeing in Paris while telling lawmakers it's time to deliver on a health care overhaul.

Grassley, the top Republican on the Finance Committee, is key to any bipartisan health care deal. Using Twitter — the Internet-based social connection service allows users to send mass text messages called "tweets" — the Iowa Republican issued two angry "tweets" Sunday morning as the president wrapped up an overseas tour.

For months Obama had left the details of health care legislation to Congress, then inserted himself firmly into the debate in recent days, including using his weekly radio address Saturday to declare "it's time to deliver" on health reform.

Grassley's first tweet: "Pres Obama you got nerve while u sightseeing in Paris to tell us 'time to deliver' on health care. We still on skedul/even workinWKEND."

Seriously. That is the GOP's point man in the Senate on health care reform. He's that petty for the world to see. And, it's only going to get worse.

Good thing the health care bill allows for 51 votes. Because, the Republicans aren't going to play ball -- despite what Obama and Senator Max Baucus think.
