Mitt-end?

It kind of sounds like Mitt is starting to give up:

In a major boost for John McCain, Republican presidential rival Mitt Romney signaled Wednesday he's not ready to commit to a costly campaign in the states holding primaries and caucuses next week.

Several officials said that on the heels of a defeat in Tuesday's Florida primary, Romney's campaign was not attempting to purchase television advertising time in any of the states on the Super Tuesday calendar.

Now would this be a boost to McCain or a boost to Huckabee? A lot of pundits think that McCain is doing so well because the conservatives are splitting between Romney and Huckabee. This could actually help Huckabee more than McCain if that's the case.
