Rick Santorum's three primary losses on Tuesday night and their implication for the future of his 2012 presidential campaign may be the hint that the Republican hopeful refuses to hear, but he may be ignoring for good cause -- after all, his main financial backer apparently has no intention of leaving his side.

Foster Friess -- the billionaire businessman and conservative Christian who recently made headlines when he said suggested aspirin was a valid form of contraception for women -- told Fox Business News on Tuesday night that he has no intention of suspending donations to Santorum's campaign, despite the fact that Republican heavyweights are already rallying around Mitt Romney as the presumptive nominee.

Friess is the top donor to the pro-Santorum Red, White and Blue super PAC, donating $1,750,000 to the outside spending organization in order to promote Santorum's candidacy. Friess is the eighth highest-spending donor to fund an outside spending group in the 2012 election cycle, according to an analysis from the Center for Responsive Politics.

Although Friess' made his comments before the results from the Wisconsin, Maryland and Washington,D.C. primaries were tallied late Tuesday, he seemed ready to accept the inevitable, even acknowledging that a Romney win in Wisconsin will be an important win for Romney.

Absolutely not. I have a lot of faith, not so much in Rick Santorum ... but I have faith in our country and that's what we are all about, Friess said when asked if he had plans to stop donating to Santorum's cause. And he's not out yet. This will be an important win for Romney ... if it occurs, but there's Pennsylvania ahead.

Friess, who at one point during the interview exclaimed that Santorum wants to save this country, recently spent nearly $9,000 to directly help the presidential hopeful's campaign by purchasing radio and newspaper advertisements in the days ahead of Wisconsin's Republican primary.

Romney ultimately came out 5 points ahead of Santorum in the state, winning 42 percent of the vote. While addressing supporters late Tuesday, Santorum said he does not intend to suspend his campaign ahead of the Pennsylvania primary, where the former senator hopes a home-state win will reinvigorate his campaign.

But, some observers say that Santorum -- who is only polling 6 percentage points ahead of Romney in Pennsylvania, according to Real Clear Politics -- would be better off dropping out of the race ahead of the April 24 primary, as a home-state loss could make a larger, more-negative statement about Santorum's political future.

Both Santorum and Friess may be putting on a positive face now, but it's worth noting that we've seen this before. After her defeat in the Iowa Caucus in January, U.S. Rep. Michelle Bachmann, R.-Minn., also insisted she, being a true conservative, would stay in the race, only to concede defeat less than 24 hours later. The same can also be said for Gov Rick Perry, R-Texas, who in mid-January vowed to continue his campaign for the nomination in Florida, before pulling out three days later -- only 48 hours before the South Carolina primary -- and abruptly endorsing former House Speaker Newt Gingrich.
