He’s resigning effective Aug. 31–14 years after he began working with Mr. Bush on his campaign for Texas governor, 10 years after they began planning a White House run, and after 79 months in the political cockpit of a tumultuous presidency.

“I just think it’s time,” he says, adding that he first floated the idea of leaving to Mr. Bush a year ago. His friends confirm he had been talking about it with others even earlier. But Democrats took Congress, and he didn’t want to depart on that sour note. He then thought he’d leave after the State of the Union, but the Iraq and immigration fights beckoned. Finally, Chief of Staff Josh Bolten told senior White House aides that if they stayed past a certain point, they were obliged to remain to Jan. 20, 2009.

“There’s always something that can keep you here, and as much as I’d like to be here, I’ve got to do this for the sake of my family,” Mr. Rove says.

Chris Matthews is saying “it had to happen.”  Why, exactly?
