Mitt Romney got what he needed from his second-home state of New Hampshire last night. It wasn’t a rocket boost into the stratosphere, but neither was it a lackluster victory that will feed doubts about him. Instead, at deadline, Romney was running close enough to John McCain’s 2008 tally of about 37 percent to post a solid win. After the stumbles of the last few days, that had to be a giant relief for the Romney campaign. Equally good news for Romney is that New Hampshire did not anoint a consensus challenger for anti-Romney voters to rally behind.
