THE MATH – Wednesday, April 23 – After Pennsylvania

8:00 a.m. Eastern Time (US)

Delegates needed to win nomination – 2,023.5 (considering status quo)
Pledged Delegates in – 2,845.0 of 3,253.0 – 87.5%

********************************************

THE MAGIC NUMBER

Here’s what we have after considering the information in the Polls section below:

Senator Obama’s Magic Number – 85 of 294 remaining superdelegates needed, or 28.9%
Senator Clinton’s Magic Number – 229 of 294 remaining superdelegates needed, or 77.9%

The Huckabee Index – 65 (or 22.1% of remaining superdelegates needed)

The “Huckabee Index” is the number of any combination of superdelegates and convention/caucus delegates that the Obama campaign needs (or the Clinton campaign loses) to make it mathematically impossible for the Clinton campaign to win the nomination, based on current delegate count and polls for upcoming contests. (Disclaimer: This is meant to poke fun at Mike Huckabee, not Hillary Clinton)
