Gov. Chris Christie's best hope in 2016 mis to run as a Democrat against Hillary Clinton...

TRENTON — Gov. Chris Christie is cashing in donations from top Democratic fundraisers and other traditionally liberal donors across the country, even nabbing the support of a handful of rainmakers aligned with President Obama and Chicago Mayor Rahm Emanuel, a Star-Ledger review of state and federal records shows.

The checks are flying into the Republican governor’s war chest from all sorts of unlikely places — the hedge fund run by liberal billionaire George Soros, for example, and the politically progressive halls of the University of California, Berkeley.

The nascent support from Democratic donors is an early sign of Christie’s fundraising prowess in a potential run for the White House in 2016, experts and Democratic donors said, and dovetails with recent polls showing him gaining popularity nationally among Democrats and independents.

Christie’s partnership with New Jersey Democratic leaders and his warm relationship with Obama after Hurricane Sandy could be enticing donors who don’t often give to GOP candidates, even if they are closer ideologically to Democrat Barbara Buono, Christie’s lesser-known challenger, political scientists and Democratic fundraisers say.
