Wealthy Republican donor Foster Friess is doubling down on the failed bet he made in 2012 on former Sen. Rick Santorum's chances of becoming president of the United States.

After hosting a fundraiser for Santorum's then-hypothetical 2016 bid in January, Friess and his wife, Lynnette, each donated the maximum of $2,700 to Santorum's campaign in late June, just days before the second-quarter fundraising deadline, according to reports filed with the Federal Election Commission Wednesday.

That $5,400 won't make or break Santorum's campaign, but it's a clear sign that Friess is solidly in the Pennsylvania Republican's corner. That could be significant. Friess donated more than $2 million to the Red White and Blue Fund, the super PAC supporting Santorum, in 2012—money that helped to keep Santorum's campaign afloat through April of that year.

Friess, who donated to both former House Speaker Newt Gingrich and former Massachusetts Gov. Mitt Romney's campaigns after Santorum dropped out of the 2012 fray, has long indicated that he would support Santorum's campaign if he ran again and has already begun attacking some of Santorum's opponents. After having lunch with Sen. Rand Paul in the Senate dining room in February, Friess criticized Paul's foreign policy views in a widely-spread email.

Still, even with the Friess' backing, Santorum's campaign had a poor quarter, raking in just over $600,000 for his presidential bid in his first month as an official candidate, about $20,000 more than he raised in his first month on the trail in 2012.
