Sen. Rob Portman broke away from his 17-year-old daughter’s tour of his alma mater, Dartmouth College, to venture an hour south here Saturday to trumpet the virtues of Mitt Romney.

Louisiana Gov. Bobby Jindal and former Minnesota governor Tim Pawlenty spent Thursday and Friday shadowing President Obama as he caravanned through Ohio and Pennsylvania, taking turns tearing into the president as they stumped in front of “Romney Victory” banners.

Sen. Marco Rubio (Fla.) is jetting to Boston this week to raise money for Romney in the candidate’s hometown, while Rep. Paul Ryan (Wis.) is headlining a Romney fundraiser in Illinois. And two weeks ago, when Romney campaigned in New Jersey, it was Gov. Chris Christie who gave the presumptive nominee some juice and bragged about having endorsed him earlier than most other Republican governors.
