Hmmm - that's interesting. And much as I like Jeb, I think people are sick of the Bush family.
the base likes him, and Hispanics seem to like him.
But what you say is true, and its part of the calculation I think. Two scenarios - Hillary wins and Jeb runs in 2012, or Jeb runs in 2016 coming in "cold" from the sidelines. In both cases, the "another Bush?" mantra is going to be a negative for him. But if he runs in 2016 having been VP for 8 years, the comfort level will be higher.
