CNN has McCain at 97 and Romney at 74. What's the disparity?
Main reasons:
1) "Party Leader" delegates...I haven't awarded them to any candidate, while CNN (in some counts) has. (this subtracts 2 from McCain and 7 from Romney)
2) I gave Romney all of the delegates from Nevada, figuring that his majority win would allow him to dominate the State Convention and impose a unit rule (with the possible exception of one delegate in CD 2). (this subtracts 4 from McCain and adds 13 to Romney)
3) I used a different system for counting Michigan delegates, awarding 2 per CD [which I think is the only sane system, should Michigan actually be penalized at the Convention]. They just took the regular delegation, chopped each candidate's numbers in half, and rounded--not really the best way to do it. (Romney +2, McCain -1).
