MACON, Ga. -- Georgia's senior U.S. senator could face a challenge from a former Macon city councilman.
Former councilman Erick Erickson is a conservative blogger and a host of his own show on WSB Radio.
On Tuesday night's broadcast, he acknowledged he's "prayerfully considering" running against Chambliss in 2014.
His statements came after an interview with Chambliss by 13WMAZ's Kenny Burgamy made national news last week.
In the interview, Chambliss said he'll consider eliminating tax loopholes and tax credits for people and corporations as part of an effort to compromise with democrats in Congress and the Obama administration to avoid a fiscal cliff crisis.
Some critics accused the senator of backtracking from the days when he signed the so-called Norquist pledge, promising never to consider a tax hike.
"That pledge I signed 20 years ago, it was valid then, it's valid now, but times have changed significantly," said Chambliss. "I care more about this country than I do about a 20-year-old pledge."
Erickson is one of his critics.
"Saxby Chambliss is waffling around like a dog off its leash for the first time," Erickson wrote in a Tuesday blog post.
He continued on to say Chambliss is part of the problem of over-spending in Washington D.C.
"A conservative from metro Atlanta could put Saxby Chabliss in peril and we should work to make that happen," Erickson capped off his post.
Even though Erickson worked on Chambliss' campaigns for re-election to the House of Representatives, he indicated on the radio Tuesday that he may be that conservative from metro Atlanta threatening the senator's seat.
Chambliss is up for re-election in 2014. He has held his seat since 2002. Previously, he served in the U.S. House of Representatives, to which he was elected in 1994.
