Chart from the Abulsme.com 2012 Republican Delegate Count Graphs page. When a candidate gets down to 0%, they have cinched the nomination. If they get up past 100%, they have been mathematically eliminated. Rather than the date on the x-axis, we show the “% of Delegates Already Allocated” as this better represents the progress through the race. Note that these numbers include estimates of the eventual results of multi-stage caucus processes which will be refined as the later stages occur.

This is the kind of day the not-Romneys wish wouldn’t happen. It is the kind of day that starts taking even the possibility of keeping Romney from getting to 1144 off the table. It highlights Romney’s superior organization and money by letting him get delegates somewhere the others probably hadn’t even thought of competing.

Neither Guam nor the Northern Mariana Islands were technically winner take all. There had been no polling at all. But when all was said and done, support for Romney here was overwhelming (actually unanimous in the small Guam Caucus) and it ended up effectively winner take all. Officially the delegates from these contests are supposed to be uncommitted, but in both locations, the result was made clear. Out of these two locations Romney gets 12 regular delegates. Also 6 super delegates from these locations also are now in the Romney column. Plus, one super delegate from the Virgin Islands also came out for Romney. That makes Romney’s take for the day a 19 delegate gain, while all other candidates were shut out completely.

So Romney’s “% of remaining needed to win” drops from 48.4% to 47.7%. Meanwhile Santorum as the closest competition goes from needing 65.5% to needing 66.4%. Santorum and the others continue to race toward mathematical elimination with each contest. Romney isn’t “racing” toward cinching the nomination yet, but he is making steady progress in that direction now. Some of the Southern states coming up may slow or reverse that process in the short term, but it getting increasingly hard to game out scenarios where Romney does not eventually get to 1144. It is just a question of how long it takes.
