Charts from the Abulsme.com 2012 Republican Delegate Count Graphs page. When a candidate gets down to 0%, they have clinched the nomination. If they get above 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.

First big primary day in awhile, and of course Romney dominates.

• New York: Romney gets all 92 delegates from today. Total in NY now Romney 94, Gingrich 1
• Pennsylvania: This is the only tricky one of the day. Delegates were elected by name, not by presidential preference. So they are all officially uncommitted, but in general these delegates do support someone, it just takes more work to figure out who. Green Papers’ initial estimate from the primary is Romney +11, Paul +5, Gingrich +4, Santorum +3, and 39 uncommitted or unknown. That is obviously a lot of uncommitted/unknown, so there will probably be future updates as the preferences of those delegates become known. Also 10 at-large delegates won’t be chosen until June and two superdelegates have yet to publicly express a preference. The total in PA is now Romney 12, Paul 5, Gingrich 4, Santorum 3, TBD 48. (GP has Romney 11, TBD 49, but I think they forgot the one Romney superdelegate.)
• Connecticut: Romney wins all 25 delegates from the primary. New CT total: Romney 26, TBD 2
• Rhode Island: Romney gets 12 delegates from the primary, Paul gets 4. New RI Total: Romney 15, Paul 4
• Delaware: Romney gets all 17 delegates from the primary. No delegates had been allocated previously and none are left, so total is just Romney 17

So, for the day… Romney +157, Paul +9, Gingrich +4, Santorum +3. Romney gets 90.8% of the delegates today. Way more than the 40.2% he needed to stay on track to get to 1144.

And with this, Ron Paul and Newt Gingrich are both mathematically eliminated. More specifically, if they were now to get 100% of the remaining delegates they would still not get to 1144. In order to get to 1144, they would actually need to take delegates away from the other candidates, either through final results in caucus states being better for them than earlier estimates, or through actual defections. Both are possible. However, neither will happen in large enough numbers to change anything, absent something catastrophic that causes Romney to actually drop out. Uh, which is highly unlikely.

For the remaining two candidates, in terms of “% of remaining delegates needed to win”:

• Romney: 40.2% -> 30.9%
• Santorum: 80.1% -> 94.5%

So, theoretically Santorum could still catch up and win by getting 95% of the remaining delegates. Needless to say that won’t happen. His already long odds were made worse by suspending his campaign.

Meanwhile, neither Gingrich or Paul have suspended their campaigns. There are indications Gingrich might do so soon despite previous vows to stay in until Tampa. Paul has shown no signs of stopping.

The 31% of the remaining delegates Romney needs to wrap this up should be very easy for him to get. But we still have to wait for the calendar. So the march goes on…

Update 2012 Apr 27 12:34 UTC:

I was incorrect about the Pennsylvania count above and had misread Green Paper’s statement. In fact the new total in Pennsylvania was indeed Romney 11, not Romney 12. There were 10 new Romey delegates added to the count, not 11. They did not forget the one superdelegate. I just got twisted around thinking the 11 was a delta from the election instead of a new total, which would have left one delegate out. But it was indeed the new new total.

This makes the total for this day Romney +156, Paul +9, Gingrich +4, Santorum +3.

That gives Romney 90.7% of the delegates for the day instead of 90.8%.

This also changes Romney’s “% needed to win” to 31.0% instead of 30.9%. Santorum’s becomes 94.4% instead of 94.5%.

These changes are too small to be visible on the graph above, but will be reflected on future updates.
