Congressional candidate Martha Zoller on Friday secured an endorsement from another major Republican figure when former presidential candidate Rick Santorum announced he is supporting her campaign for Georgia's new 9th District seat.

A former radio talk show host from Gainesville, Zoller had already collected endorsements from former Alaska Gov. Sarah Palin and former presidential candidate Herman Cain. Santorum also announced Wednesday that Patriot Voices -- a nonprofit organization he is leading to defeat President Barack Obama -- is also supporting Zoller.

"Martha is an outspoken advocate for the principles of faith, family, freedom, and opportunity that we at Patriot Voices strive to advance," Santorum said in a prepared statement. "Martha shares our commitment to the value of each and every life, that economic success is found in free markets, and that our government must be limited and accountable to the people.

Zoller's opponent in the Aug. 21 GOP primary runoff -- state Rep. Doug Collins -- took aim Wednesday at the endorsements she has received from out-of-state Republicans, including Palin.

"Over the next 19 days, we have to come together and show once again that we are the 9th District — not governors from Alaska and media celebrities from D.C.," he said in a news release Wednesday.

Collins, also from Gainesville, has collected endorsements from former U.S. Sen. Zell Miller, also a former governor, and Georgia House Speaker David Ralston.

Zoller slapped at Collins in her own news release Thursday, calling him an "establishment-backed" candidate who had "all the money, all the advantages, and all the powerful insiders behind him."
