All the contenders for chair of the Republican National Committee promise to raise money and to spend it wisely. But which candidates did these hopefuls consider good investments for their own cash?

We’re rather ignorant on this topic because their political donations are so few. Looking at filings with the Federal Election Commission, however, we get a hint. Saul Anuzis, for instance, donated $1,000 to George W. Bush in 1999. In other words, he wasn’t a McCainiac.

The only donation on file for Gentry Collins is $2,100 for Mitt Romney in 2007 — Collins was working for Romney at the time. And the only donation to a presidential candidate on file for Reince Priebus is $1,000 to Tommy Thompson in March 2008. (Side note: Thompson dropped out of the race in August 2007.)

Ann Wagner kept her money close to home, donating thousands of dollars to Missouri’s Republican senator Kit Bond, former senator Jim Talent, and senator-elect Roy Blunt.

The candidate whose donations range widest is Maria Cino. She gave $1,000 to Mike Castle in June 2010, $1,000 to Jane Norton in November 2009, and $1,000 to Kelly Ayotte in July 2010. She also gave $500 to Marsha Blackburn in December 2009 and $500 to George Allen in June 2006. Cino’s many years of donating seem to be paying dividends as she prepares her run.
