Marco Rubio's highly touted debate performance on Wednesday has already yielded a significant tangible benefit: The Republican presidential candidate has snagged the support of mega-donor Paul Singer, in a move that will be widely seen in the political world as a blow to struggling rival Jeb Bush. One of the party's most prolific and hard-to-please donors, Singer gave more than $16 million to candidates and political committees in the last four years, according to records on file with the Federal Election Commission. Fiscally conservative and socially moderate, the hedge-fund manager has donated to conservative candidates and causes, such as pro-Israel groups, former Ambassador John Bolton, and the Tea Party Patriots, but he has steered many of his contributions to his own super political action committee, American Unity, which supports Republicans who back gay rights. He gave $1 million to Restore Our Future, the super-PAC supporting Mitt Romney's 2012 presidential campaign, and he supported former New York City Mayor Rudy Giuliani's 2008 White House bid.
