June 16, 2012- Casino billionaire Sheldon Adelson, whose net worth makes him one of the world's richest men, is on a check-writing spree that will soon bring his total political contributions in this election cycle to at least $71 million, according to sources familiar with his spending. That money is spread across the spectrum of GOP super PACs, which are required to disclose donors, and nonprofits, which are not.
Adelson and his wife, Miriam, along with other family donations, have already reached $36 million, including $10 million to the Romney-backing super PAC Restore Our Future that was reported this week. But two GOP fundraisers familiar with his plans say that Adelson has given or pledged at least $35 million more to three conservative nonprofit groups: the Karl Rove-linked Crossroads GPS, another with ties to billionaires Charles and David Koch and a third with links to House Majority Leader Eric Cantor (R-Va.).
