I don't know Keller, but was never a fan of Jeb Bush. What is his attraction?
He was the Bush that was supposed to be the 43rd President. Not W.
He ran for Florida Governor the same year George ran in Texas...only everyone expected Jeb to win and George to lose. Jeb would use the Governorship to groom him for President.
Only no one expected him to lose to Lawton Chiles. George beat ma Richards and the rest is history.
Jeb is merely trying to get to the position he feels he was groomed for.
