In Maine, it looks like the Ron Paul campaign's claim that the fix was in has some merit :

Pressure is on the Maine Republican Party to reconsider its weekend declaration that Mitt Romney won the state’s caucuses.

The Maine GOP announced Saturday that Romney narrowly edged Ron Paul, 39 percent to 36 percent, in a nonbinding presidential preference poll taken during the caucuses. The margin was fewer than 200 votes...All along, state GOP officials said communities knew that their votes would not be included in the final results if they did not hold their caucus by Feb. 11.

However, a review of the town-by-town results released Saturday by the Maine GOP suggests that some communities that had caucused prior to Feb. 11 were not counted.

If mainstream Republicans want to obscure results of caucuses, they're going to have to do better than that. The press is going to start paying very close attention to caucus results from here on out.
