By all appearances, former Florida Gov. Jeb Bush is a man on a mission.

His itinerary for the next several weeks includes stops in Tennessee, New Mexico and Nevada to appear with Republican candidates in this fall's elections or help them raise money for their campaigns.

And then he speaks at a dinner ahead of a Republican Jewish Coalition meeting featuring several potential Republican presidential contenders at the Venetian Hotel in Las Vegas. The hotel is owned by casino magnate Sheldon Adelson, who gave over $100 million to Republican candidates in 2012.
