One David Sparks in the Boston Globe:

Romney is still due his “Comeback Kid” moment with the voters. McCain was struggling for campaign money and lost members of his staff last summer but made his comeback. Hillary Clinton lost Iowa and battled back in New Hampshire. The media will have second thoughts about ending this race too early. A new-look Romney, perhaps with more humility and a sharpened message, might give his campaign a second wind.

Oh, and on that “electability” issue, he adds:

As the candidate to the right of Romney, Huckabee’s votes might go Romney’s way if he leaves the race. The problem will be the stretch for Huckabee’s base from Conservative Christian to Mormon. It’s still worth seeing how “Romney-Huckabee” looks on a sign.
