WASHINGTON (AP) — John Kerry says Republican John McCain doesn't have the judgment to be president.

If that's the case, then it's probably a good thing McCain rejected overtures from Kerry, the Democratic presidential nominee in 2004, to form a bipartisan ticket and run with Kerry as his candidate for vice president.

Kerry had no kind words for his Senate colleague Sunday, accusing McCain of poor decision-making on everything from backing tax cuts for the wealthy to making support for continuing the U.S. military presence in Iraq the centerpiece of his presidential campaign.

"John McCain ... has proven that he has been wrong about every judgment he's made about the war. Wrong about the Iraqis paying for the reconstruction, wrong about whether or not the oil would pay for it, wrong about Sunni and Shia violence through the years, wrong about the willingness of the Iraqis to stand up for themselves," Kerry, who supports Democratic presidential candidate Barack Obama, said on CBS' "Face the Nation."

McCain adviser Sen. Lindsey Graham, R-S.C., said McCain was the one who stood up to the administration and urged President Bush to send more U.S. troops to Iraq to help control violence. Obama did not support the addition of troops.

"We're winning because John McCain understood Iraq better than anybody else," Graham said. "The surge has worked. The political, economic and military progress in Iraq is undeniable."
