Jeb Bush prepares to give traditional campaign a makeover

DES MOINES, Iowa -- The traditional presidential campaign may be getting a dramatic makeover in Jeb Bush's bid for the White House as he prepares to turn some of a campaign's central functions over to a separate political organization that can raise unlimited amounts of money.

The concept, in development for months as the former Florida governor has raised tens of millions of dollars for his Right to Rise super PAC, would endow that organization not just with advertising on Bush's behalf, but with many of the duties typically conducted by a campaign.

Should Bush move ahead as his team intends, it is possible that for the first time a super PAC created to support a single candidate would spend more than the candidate's campaign itself -- at least through the primaries.
