Mitt Romney's two steps forward, one flub back presidential campaign continues its tantalizing progress toward a total victory that always seems just ahead.
The likeliest route is that Romney pulls off a clean win by the time the last state votes in June.
Rick Santorum and Newt Gingrich are trying to prevent that tidy Romney finish by sticking in the contest and drawing away votes. That strategy comes as Republicans are eager to choose a champion and turn the party's attention to defeating President Barack Obama.
Superdelegates could help speed up the finish.
There's also the potential for a contested convention, with Santorum grabbing the chance he's been waiting for.
And how about a brokered convention? In that case, the powerbrokers toss out the candidates and draft someone new.
