Republican Primaries

Aaron Burr vs. Alexander Hamilton - The inspiration behind Republican primaries?

So in case you haven't noticed, we've been in the middle of the primaries for some time now. And while I've had plenty of interest in these races, I haven't had the time to make fun of - excuse me - evaluate them.
I've decided to start with the Republican races. First of all, McCain appears to have sealed the deal, which seems to be quick to do in the Republican primaries.
Republican primaries are brutal win all or lose completely contests. And in these winner-take-all primaries, losers drop out fast and, eventually, happily endorse the leading candidate.

Or something like that...
