Think Progress - A Think Progress examination of New Jersey campaign finance records for Booker’s first run for Mayor — back in 2002 — suggests a possible reason for his unease with attacks on Bain Capital and venture capital. They were among his earliest and most generous backers.
Contributions to his 2002 campaign from venture capitalists, investors, and big Wall Street bankers brought him more than $115,000 for his 2002 campaign. . While the forms are not totally clear, it appears the campaign raised less than $800,000 total, making this a significant percentage.
In all — just in his first Mayoral run — Booker’s committees received more than $565,000 from the people he was defending. At least $36,000 of that came from folks at Romney’s old firm.
