"I'm all too familiar with the quote," said McCain, who has since smoothed things over with his colleague.
McCain, whose temper has earned him the nickname "Senator Hothead" by more than one publication, said he does get angry -- about corruption and runaway spending in Washington. "You know something, the American people are angry, too, and they're not going to take it anymore," he said.

If he really had a temper problem, McCain said, he would not have been able to work with fellow senators such as Edward M. Kennedy, a Massachusetts Democrat; Russ Feingold, a Wisconsin Democrat; and his friend Joe Lieberman, the 2000 Democratic vice presidential nominee who now is an Independent.

Perhaps a swing and a miss.

British Foreign Secretary Derides Russia Policy Backed by McCain
By Glenn Kessler
Sen. John McCain has repeatedly proclaimed that it is time to kick Russia out of the "Group of Eight" organization of industrial powers, even before Russia's recent conflict with Georgia. But the idea has not been embraced by many foreign policy experts, who tend to view it as needlessly provocative.

Today, the top diplomat of one of the U.S.'s closest allies, British Foreign Secretary David Miliband, weighed in, calling the notion "knee-jerk," though he did not mention McCain's name.
