The vast majority willing to speak on the record say they haven’t decided whom to support in 2016. Almost all say they are wrestling with conflicting loyalties to Romney, former Florida Gov. Jeb Bush and other potential Republican hopefuls such as Sens. Marco Rubio of Florida and Lindsey Graham of South Carolina, as well as Govs. Mike Pence of Indiana, Scott Walker of Wisconsin and Chris Christie of New Jersey.

If Romney hopes to win the nomination, he will have to work overtime to reconstitute the fundraising network that fueled his most recent White House bid and beat back potential competitors. Bush, in particular, is already trying to poach key Romney supporters who have the potential to raise, or “bundle,” millions of dollars for the candidate they ultimately decide to support.

To wit: Bush spent Tuesday afternoon courting some of Washington’s most powerful lobbyist-donors — including many top Romney 2012 fundraisers — around a dark-wood oval table in the bare-walled conference room at the offices of the National Association of Wholesaler-Distributors.
