Charts 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. The first chart is by date, the second is by “% of Delegates Already Allocated”. These numbers include estimates of the eventual results of multi-stage caucus processes which will be refined as the later stages occur.

So… this is it. Long ago any realistic possibility for any non-Romney to win the nomination disappeared. With today’s update the already long odds for the non-Romneys to keep Romney from getting to 1144 essentially drop to zero. This is over. Romney wins. Without any sort of brokered convention. For something else to happen now we’d need some event that was so earth shaking that Romney dropped out. This is extremely unlikely.

Details below.

We have updates from four contests. In alphabetical order:

• DC: DC is winner take all, Romney gets all 16 delegates.
• Maryland: Maryland is not actually winner take all, you get some delegates for winning the state, and then more delegates go to the winner of each congressional district. But Romney not only won the state, but every congressional district. So Romney gets all 37 delegates.
• North Dakota: North Dakota had the first round of its process in March. At that time the delegate estimate was Santorum 11, Paul 8 , Romney 7 , Gingrich 2. But the state Republican Convention happened last weekend, and Romney supporters owned the parliamentary process, taking the lion’s share of the delegates despite coming in third in March. That’s how it works in caucus states sometimes. It took a couple days for Green Papers to confirm a new estimate, but it now looks like Romney 20, Santorum 6, Paul 2. So the net today is Romney +13, Gingrich -2, Santorum -5, Paul -6.
• Wisconsin: Wisconsin also allocates some delegates based on both state and CD winners. Romney won the state. Romney won 5 CDs. Santorum won 3 CDs. So overall we have a delegate count of Romney 33, Santorum 9

Add those up and we have a net total for today of Romney +99, Santorum +4, Gingrich -2, Paul -6 Obviously Romney completely dominated the day.

In terms of “% of remaining delegates needed to win” we have this:

• Romney: 47.3% -> 42.5%
• Santorum: 71.8% -> 77.5%
• Gingrich: 80.5% -> 87.5%
• Paul: 86.8% -> 94.6%

The also-rans who left the race early on… Bachman, Huntsman and Perry… are mathematically eliminated after today. Paul, Gingrich and Santorum will inevitably join them soon.

The blocking Romney option? At this point the non-Romneys collectively would need to get 57.5% of the remaining delegates. So far they have managed 42.6% of the delegates. A change of this sort, while not mathematically impossible, would be unprecedented, especially since we are in the phase of the campaign where it is clear Romney is winning and the others are losing. People just stop voting for losers. As things go on, the % of delegates the non-Romneys get will probably actually decline. A major increase is just not going to happen.

It is over.

(We will of course continue to update these charts until Romney actually gets to 1144 however.)
