In a last-ditch move, Adelson and his wife, Miriam, added another group to their list of beneficiaries and recently became first-time donors to Karl Rove's conservative super PAC American Crossroads.
The Adelsons combined to give American Crossroads $20 million on Oct. 19 and another $1.5 million each on Oct. 30, according to the Federal Election Commission. That $23 million is in addition to the millions they dropped on like-minded super PACs -- such as Restore Our Future, Winning Our Future and Congressional Leadership Fund. Various news reports have said that Adelson also gave tens of millions of dollars to American Crossroads' 501(c)(4) affiliate, Crossroads GPS, which doesn't have to disclose its donors.
The FEC's post-election reporting deadline was Thursday, and American Crossroads filed a report covering receipts and expenditures between Oct. 18 and Nov. 26. Almost all the donations came in by Nov. 6, Election Day.
The super PAC finished with about $1.5 million on hand after bringing in $37.3 million from individual donors in those three weeks. Overall in 2012, American Crossroads spent about $104 million on independent expenditures, $41.7 million worth of them in the most recent reporting period. Almost all of the money went to oppose Democratic candidates, according to the Center for Responsive Politics.
