Majority Leader Eric Cantor was handed a shocking upset defeat Tuesday night, but he didn’t go down alone – Blackstone Group (BX) bet big on the moderate establishment Republican and now that investment is down the tubes, as Cantor is now on a path to private citizenship.

Washington and the Republican machine are still reeling after the second-most powerful man in the House was dethroned by a tea party Republican primary challenger who was outraised in funding 25 to 1 by the eight-term Cantor.

Of the more than $5 million Cantor spent defending his Richmond, Virginia district seat in the primary, a good chunk of that came from Blackstone, according to OpenSecrets.org. Cantor raised a total of $5.4 million.

Blackstone Group is now the largest landlord in America, via Invitation Homes, and it was also Cantor’s largest corporate donor in this election cycle.

More than 10% of Blackstone’s 2014 election cycle donations to individual candidates went directly to Cantor.

During this cycle, the company has donated $613,125 to candidates, of which $65,000 went to Cantor.

Blackstone Group spent the past two years building its empire of single-family rental homes via subsidiary Invitation Homes, spending $7.5 billion to acquire 40,000 houses. The private-equity firm sells bonds backed by lease payments.

Cantor lost to economics professor David Brat, who targeted Cantor’s support of a more liberal immigration and amnesty policy. He raised a mere $206,000 and spent just $122,000 for his whole campaign.

Cantor, in contrast spent almost $168,000 on steakhouses during the election campaign.

While there are many reasons for Blackstone or any other business to support a high-ranking House member, Blackstone would certainly benefit in an increase of immigrant workers who are more likely to rent than buy.
