The New York Times (among others) have noted the silence of Jeb Bush in the days leading up to the Florida Primary.

An unspoken question hovering over the Republican presidential race here is why Mr. Bush, the state’s popular former governor and heir to the nation’s aging political dynasty, has not added his voice to the party establishment’s support for Mr. Romney in his increasingly bitter duel with Newt Gingrich.

From where I sit, the answer is obvious.

The bitterness and division that have increasingly come to characterize the GOP nomination process is likely to result in no clear frontrunner headed into the convention in August. The degree to which the party is split means that we are quite likely to see no candidate get the nomination on the first ballot – at which point the delegates are released from their commitments and are free to switch to one of the other candidates – or to someone else who has not been in the running up to that point. By staying out of the conflict in Florida, Jeb Bush will have positioned himself to be the choice of the delegates on the second or third round of balloting. He has both conservative and establishment credentials – and by not making an endorsement he can serve as a unifier.

And if there is not a brokered convention and one of the current crop of candidates is the nominee, Jeb Bush is well positioned to be the 2016 nominee if that candidate loses.

Seems to me that the better question to ask is why Jeb Bush would even want to make an endorsement at this point.
