DES MOINES--GOP White House hopeful Jon Huntsman--who is very wealthy-- is trying a new fund-raising gimmick: he announced Sunday he will "match" contributions "dollar for dollar" from individuals with his own money.

Huntsman--who did not campaign in Iowa for the first-in-the-nation Tuesday cacus vote has instead focused on New Hampshire--where he stumped Sunday while most of his rivals were in the Hawkeye state.

Federal law allows a candidate to pour his or her own money into a campaign in unlimited amounts--while individuals face donor caps.

Asking for "matches" is a fund-raising tactic used in the political and non-profit worlds.

"from now until midnight Wednesday, Mary Kaye and I will personally match - dollar for dollar - every new donation our campaign receives," Huntsman wrote in an e-mail.

"In just a few minutes, I will be holding a town hall in Deerfield, New Hampshire - our third event of the day, and 143rd event in the state. With only nine days to go until New Hampshire's primary, it is critical that we have the resources - both on the ground and on TV - to compete with Mitt Romney.

"That is why I am giving you the opportunity to double the impact of your donation. Whether you contribute $10, $100, $1000 or the maximum amount of $2,500, Mary Kaye and I will personally match every dollar you donate."

Huntsman, of course, may have been planning to pour in his own money anyway--at least this way he is trying to leverage his cash.
