An easy one to answer. Regarding the alleged plot by Iran to assassinate the Saudi ambassador to the United States, “Attorney General Eric Holder last week announced the attempt, which he said was ‘conceived, sponsored and … directed from’ the Iranian government. Asked by host Candy Crowley on CNN’s ‘State of the Union’ whether Obama has been too soft on Iran, [Sen. John] McCain replied, ‘I think his policy of engagement with Iran has clearly been a failure.’ ” And so have sanctions.

It’s not simple to mesh these two gurus’ views; in fact, they pretty much take opposite positions on a host of issues. “Republican presidential candidate Herman Cain said Sunday that the writings of former United Nations ambassador John Bolton and former Secretary of State Henry Kissinger have shaped his views on foreign policy.” Unfortunately, David Gregory didn’t press him to reconcile the two.

The cinch for the vice-presidential candidate is Virginia Gov. Bob McDonnell, if the GOP presidential nominee wants to share the ticket with a guy who has a 70 percent approval rating in a key swing state.

If Texas Gov. Rick Perry is going “positive,” it’s not so clear why virtually all his press e-mails are negative barbs directed at Mitt Romney. Perry’s guru David Carney says, “This whole idea that you have to attack Mitt Romney — that’s pedestrian thinking.” I can’t imagine anything more pedestrian than a superPAC run by the governor’s longtime ally and donor Mike Toomey.

It’s hard to explain how a piece ran in the New York Times that is rather favorable to Romney and to religion. Editors must have been asleep at the wheel to let that get through. Worth reading in full.

Bill Kristol says it’s difficult for Obama to win on his record so his current gambit makes some sense. “There’s very little he can do, he must think, to get the economy going now. He’s foolishly bought into the policies that have gotten us into the mess we’re in. And unless he’s going to fire Ben Bernanke tomorrow and fix the ridiculous Fed policy, et cetera, he’s stuck with these policies. So why not try to blame House Republicans?”

Chuck Todd says it’s tough to defend 9-9-9. “It’s gotten plenty of play, but suddenly you go underneath the hood and it’s not hanging out so well.”

Charlie Cook finds it impossible to imagine the GOP nominee will be someone else other than Perry or Romney. “Cain seems to be functioning as a parking place for conservatives who have grown disillusioned or who harbor reservations about the previous flavors of the month. . . . .Romney exudes intelligence and competence, and every debate makes him look more presidential and more like someone who would be a very strong favorite to win a general election — if he wins the GOP nomination. Whether he can overcome right-wing doubts will largely hinge on whether Perry makes the turn from being a Texas candidate into being a national one, scratching that ideological itch that conservatives have. If he doesn’t, Republicans may hold their noses and go with the guy that is a very good bet to beat President Obama next November.”
