The former Utah governor and U.S. ambassador to China will match donations to his campaign dollar-for-dollar until midnight Sunday, according to a statement from Team Huntsman.

“Whether you contribute $10, $100, $1000 or the maximum amount of $2,500, Mary Kaye and I will personally match every dollar you donate,” an email from Huntsman read. “At every campaign stop, I can feel the momentum building for our campaign.”
