The Forward reports: It’s been a tough night for Jewish political mega-donor Sheldon Adelson, the Las Vegas casino magnate who was the biggest political donor of the election cycle.

Adelson and his wife had backed Mitt Romney with $20 million in donations to the pro-Romney super PAC. But his spending on failed Republican candidates went well beyond the top of the ticket.

Three additional Adelson-backed candidates lost their races tonight. In Virginia, Tim Kaine won the governorship over George Allen, whose super PAC had received $1.5 million from Adelson. In Florida, Bill Nelson won the Senate seat over Connie Mack, who Adelson had backed with $1 million. And in New Jersey, Adelson-backed Orthodox Jewish Republican Shmuley Boteach lost to Democratic incumbent Congressman Bill Pascrell.

One bright point for Adelson on a grim evening could be Florida’s 18th Congressional District, where Adelson-backed Republican Allen West is holding on to a slim lead over Democrat Patrick Murphy.

But that glimmer appears already lost. As of 7AM Eastern, Murphy is the projected winner.
