Internecine triangulation? Jeb Bush has (apparently) come out against Bush's plans to grab more powers for the military. From "Think Locally On Relief":

As the governor of a state that has been hit by seven hurricanes and two tropical storms in the past 13 months, I can say with certainty that federalizing emergency response to catastrophic events would be a disaster as bad as Hurricane Katrina.

There must be something else going on. Perhaps he's trying to portray himself as the more conservative one or something.
