Wow! I bet the Democrats are dancing in the streets:

Karl Rove, the architect of President Bush’s two national campaigns and his most prominent adviser through 6-1/2 tumultuous years in the White House, will resign at month’s end and leave politics, a White House spokeswoman said this morning.
Bush plans to make a statement with Rove on the South Lawn this morning before the president departs for his ranch near Crawford, Tex. Rove, who holds the titles of deputy chief of staff and senior adviser, has been talking about finding the right time to depart for a year, colleagues said, and decided he had to either leave now or remain through the end of the presidency.

Rove told Gigot that he remains confident Bush will recover politically despite his low approval ratings. “He will move back up in the polls,” Rove said. And he said Republicans could still retain the White House next year. The Democrats are likely to nominate Sen. Hillary Rodham Clinton (N.Y.), “a tough, tenacious, fatally flawed candidate,” he said, but Republicans have “a very good chance” of beating her.
Rove laughed off his own reputation as the svengali of the Bush presidency. “I’m a myth,” he said. “There’s the Mark of Rove. I read about some of the things I’m supposed to have done and I have to try not to laugh.”
