Finally, the rules open the door to a contentious convention, if not a contested one.

Why? Because if there’s sentiment for a fight over a platform plank, or whether convention rules outlaw winner-take- all voting, all the dissidents need is 25 percent of the votes in the respective committees — a mark the combined anti-Romney forces might well achieve. Further, if Gingrich wants his name put in nomination, all he needs is a plurality of delegates — not a majority — in five states. He already has that plurality in South Carolina and may yet pick up pluralities in four more states along the way.

If those adamantly opposed to Romney wind up with this kind of strength, it means they will have the power to start rules fights or demand the gold standard be included in the platform. They may be able to offer their own vice-presidential nominee or throw the timing of important speeches into chaos.

I may be getting ahead of myself; the convention isn’t until August. Maybe it’s better to focus on the debate in Arizona in three weeks. I wonder how long it will take for Gingrich to attack the moderator?
