Jonathan Bernstein explains what is at stake:
Romney has a large delegate lead, which will most likely be even larger after Tuesday. What will really matter is whether the party and the press agree that it's essentially over. This will be the first night since South Carolina where, if things go well for Romney, we could reach that point. But if he has yet another setback, the wait will go on.
Kilgore watches the media:
keep your eye on media coverage of Super Tuesday as either a mega-primary with many fronts (ten, to be exact), or as Ohio plus a bunch of other places. The latter interpretation could make Ohio matter more than the delegate count or the number of primaries and caucuses won. Romney, of course, could make the question moot by winning the Buckeye State as well. But then again, it would be perfectly in character for him to find another way to inform Ohioans he could buy and sell the lot of them with pocket change.
As of today, there is no sign of Newt abandoning the race over the weekend. But if he gets crushed everywhere except Georgia on Tuesday, he will have to sit down with Callista and with Sheldon Adelson and reconsider his options. And one of those options, surely, must be calling it quits and swinging his support behind Santorum.
