McCain's flip-flop on radical executive power and illegal spying actually happened a few days ago, but I'm glad Charlie Savage elevated it by covering it in the New York Times.

A top adviser to Senator John McCain says Mr. McCain believes that President Bush’s program of wiretapping without warrants was lawful, a position that appears to bring him into closer alignment with the sweeping theories of executive authority pushed by the Bush administration legal team.

In a letter posted online by National Review this week, the adviser, Douglas Holtz-Eakin, said Mr. McCain believed that the Constitution gave Mr. Bush the power to authorize the National Security Agency to monitor Americans’ international phone calls and e-mail without warrants, despite a 1978 federal statute that required court oversight of surveillance.

Mr. McCain believes that “neither the administration nor the telecoms need apologize for actions that most people, except for the A.C.L.U. and trial lawyers, understand were constitutional and appropriate in the wake of the attacks on Sept. 11, 2001,” Mr. Holtz-Eakin wrote.

In an interview about his views on the limits of executive power with The Boston Globe six months ago, Mr. McCain strongly suggested that if he became the next commander in chief, he would consider himself obligated to obey a statute restricting what he did in national security matters [...]

Mr. McCain’s position, as outlined by Mr. Holtz-Eakin, was criticized by the campaign of his presumptive Democratic opponent in the presidential election, Senator Barack Obama of Illinois. Greg Craig, an Obama campaign adviser, said Wednesday that anyone reading Mr. McCain’s answers to The Globe and the more recent statement would be “totally confused” about “what Senator McCain thinks about what the Constitution means and what President Bush did.”

“American voters deserve to know which side of this flip-flop he’s on today, and what he would do as president,” Mr. Craig said in a phone interview.
