The primary process is a complete dog's breakfast.
Also, it's never the same twice. You can get an idea of the complexity at the Wikipedia article, and it's educational to click back to the 2008 Republican primary article, too. Note the changes in dates, the difference in "Super Tuesday," and all the rest.
Given the schedule, I'm pretty much just watching the process from the cheap seats (I get to vote in June. Guess how much difference that's going to make by then).
I really doubt it's going to go all the way to the convention. As I said, I doubt it's still going to be up in the air by June.
