It's hard out there for a reshuffling candidate. The inside-the-beltway media is circling, waiting for fresh carrion ("Death Watch," reads today's headling on The Note; "Dear John:" says First Read). And McCain himself, "visibly tired," according to the Politico's John Bresnahan, ended up not only in an extended debate with California Senator Barbara Boxer on the floor, but also in a heated argument with fellow Republican Senator George Voinovich off the floor.

Meanwhile, in the Senate, the White House took another hit as Maine Senator Olympia Snowe became the second Republican to sign on to a bill that would require troops to begin leaving Iraq in 120 days. Senator Gordon Smith, an Oregon Republican, is also on board.

Establishing a firm deadline for withdrawal will take 60 votes to overcome a filibuster. "If there aren't 60 votes [now], I can assure you there will be in September," Snowe told the Chicago Tribune's Jill Zuckman. By the way, could one of those 60 votes be from Snowe's colleague Susan Collins? She faces Maine voters in 2008, and while she hasn't signed onto the bill that would force withdrawal, she has voiced a healthy amount of skepticism about the President's approach to the war.

Coming under increased scrutiny about his age, New Jersey Senator Frank Lautenberg did something today we hope never to actually experience: "I can send you a copy of the colonoscopy I just took. It's really something to admire," Lautenberg told the Newark Star-Ledger's Tom Moran. A Quinnipiac University poll out yesterday showed 54% of New Jersey residents thought Lautenberg, 83, was too old to run for another term, while 40% disagreed.

Wealthy real estate developer Anne Evans Estabrooks and state Assemblyman Michael Doherty are the two main Republicans thinking about taking on Lautenberg. One Republican consultant who has managed races in New Jersey tells us to keep an eye on Assemblyman Bill Baroni as well. Baroni, elected in an otherwise Democratic district, is running for State Senate this year, and a good showing could encourage him to make a federal bid in 2008.
