Early voting for Jeb Bush as Wall Street bucks flow to GOP contender

Jeb Bush kicks off presidential campaign

Republican candidate Jeb Bush only just formally launched his presidential bid in Miami, but his campaign has already attracted a robust roster of Wall Street donors.

Supporters from the financial community include private equity executives, hedge fund managers, bankers and more, based on a CNBC analysis of fundraising gala invitations and media reports. A few of these marquee names were willing to sing Bush's praises publicly.

"He's a deeply substantive, compassionate person who is a proven problem solver," said Kenneth Juster, a managing director at New York-based private equity firm Warburg Pincus. Juster is a part-time policy advisor to the Bush campaign, and recently traveled with the candidate to Europe.

Others in the private equity community to support Bush include Kolberg Kravis Roberts (KKR) executives Henry Kravis, Alex Navab, Ken Mehlman and Zack Pack; David Knower, chief operating officer of a Cerberus Capital Management unit in Germany; Marc Spilker, until last year the president of Apollo Global Management; Brad Freeman of Freeman Spogli; Andrew Saul of Saul Partners; Anthony de Nicola of Welsh, Carson, Anderson & Stowe; and Barry Volpert of Crestview Partners.

From hedge funds and other so-called alternative investors, there's Scott Kapnick, CEO of JPMorgan Chase investment unit Highbridge Capital Management; Sander Gerber of Hudson Bay Capital Management; Neuberger Berman Group CEO George Walker (a Bush cousin); and Richard Kayne of Kayne Anderson Capital Advisors.
