Manchester, New Hampshire (CNN) - For all that was new about Mitt Romney speaking before a tea party crowd, the most striking fact was how little was different.

Aside from a new line about his short time spent in public office, when Romney spoke to a tea party rally in Concord, New Hampshire, he stuck with the same pro-business message he's used at campaign events across the country.
