@Cycloptichorn,
At this point, pretty much nobody can jump in and win the nomination via a regular primary -- too many deadlines have passed to even get names on the ballot, for example.
I find the brokered convention idea to pretty far-fetched too, but it's at least possible.
So, my interest is not really about whether Mitch Daniels can be the nominee, but what the reaction is, for what it indicates about the race in general.
