Sen. Lindsey Graham was the sole Republican on the Senate Judiciary Committee to vote in favor of Sonia Sotomayor. A few days later, he co-signed an op-ed in The Washington Post with six Senate Democrats and four other Senate Republicans that began, "We refuse to let partisanship kill health reform." If there's a deal to be made on health care, he'll probably be at the center of it. Graham (S.C.) spoke with The Post's Ezra Klein about reform, the pitfalls of bipartisanship and the difference between buying a car and having a heart attack.
