This is a risky strategy for the Romney campaign. First, Iowa voters are notoriously dislike negative campaigning and so Romney risks a backlash in a state he really needs to win after devoting unparalleled resources and effort to it. Second, if these attacks don’t work they’ll inoculate Huckabee against the charges down the line. Third, the rest of the GOP field don’t like Romney much—partly because of his hypocrisy, the man who is attacking others for wanting to let the children of illegal immigrants go to university at the in-state rate has been caught with illegals working on his lawn twice—and can use Romney’s negative ads as a good chance to take a swipe.
The Democratic race might be close but it is predictable: either Hillary Clinton or Barack Obama will end up as the nominee. On the Republican side, there are five guys still in with a real chance of winning the nomination and no one can really tell you how this is going to pan out. Expect the fight to get very nasty before it's all over.
