◼ Mitt Romney's Moment = Peggy Noonan/Wall St. Journal

It's been a good week for Mitt Romney. The polls are up, he's just off a two-day swing through Connecticut and New York where he hauled in big donors and hard money, and he swept the GOP primaries in Kentucky and Arkansas.

That, in my view, is the course the president has put us upon." If Barack Obama is re-elected, "it will be very difficult to get off that path. If I'm elected, I will usher in a period of economic vitality" that will leave the world "surprised."
