Casino mogul Sheldon Adelson gave $5 million to YG Action Fund, a super PAC run by two former top aides to House Majority Leader Eric Cantor (R-Va.).

The donation helped YG Action Fund achieve its best fundraising quarter since opening shop last year. The super PAC raised just more than $5.3 million from April through June.

The money came just in time for the group to spend more than $500,000 to boost Richard Hudson, a former House chief of staff, in the runoff for North Carolina’s 8th district on Tuesday.

Roll Call sat down with YG Action Fund’s leadership last week to discuss their goals for the 2012 cycle.

This isn’t the first time this year Adelson has made a multi-million dollar donation to help House Republicans. Earlier this year, Adelson and his wife donated $5 million to the Congressional Leadership Fund, a super PAC devoted to boosting Republicans in House races.
