More Christie cash heading to Romney

Mitt Romney has secured the backing of hedge fund mogul and major GOP bundler Paul Singer, Romney's campaign confirmed Thursday.

Singer adds to the list of big-name supporters of New Jersey Gov. Chris Christie (R) who have gotten behind Romney since Christie announced Tuesday he wasn't running for president. Home Depot co-founder Kenneth Langone, who vehemently urged Christie to run, switched to Romney's camp within hours of Christie's announcement.

The founder of Elliott Management Corp., Singer raised high-dollar amounts for both former President George W. Bush and Rudy Giuliani.

Singer's support is another sign that major GOP players who had been holding out until the 2012 presidential field settled are betting on Romney as the safest, most viable candidate to take on President Obama. It also underscores the notion that Rick Perry has struggled to make inroads with the Wall Street financiers and elements of the Republican establishment.
