The finally volleys in the Republican primary contest in a new north Georgia congressional district have dovetailed on one familiar refrain: my opponent lies, mostly about me.

State Rep. Doug Collins blanketed the ninth district this week with a new mailer torching rival Martha Zoller as smear monger compensating for moderate positions on abortion, taxes and civil unions for gays and lesbians.

“[S]he’s now saying things about Republican Doug Collins’ record as Governor Deal’s floor leader that simply aren’t true,” the reverse of the new mailer reads. “But shouldn’t Martha spend less time smearing her opponent and more time explaining her own zany views?”

Zoller’s responded in kind on Friday, tapping Herman Cain to record a new robo-call in which the former presidential hopeful levels the mailer as an establishment attack on a “shake-up-the-status-quo-conservative.”

“You see the establishment is scared of Martha Zoller, and they should be,” Cain, who endorsed the conservative radio talker-turned-pol in January, says in the tape. “It showed today from her opponent, Doug Collins, who launched a false, negative attack against her. Apparently, they think we are stupid.”

Cain closes the recording with a plug for Zoller’s new microsite, CollinsLies.com, that challenges the negative statements made by her rival.

The fact-checking website dissect seven accusations–support for abortion, gay marriage and drug legalization, among others–that taken in sum by party faithful would render the firebrand a rather moderate breed.

But little more than two weeks removed from the state’s primary election, voters will soon determine which of the pair’s lies are more egregious.

UPDATE: Collins has launched a complimentary digital component to the “zany” offensive, featuring nearly a dozen video clips of then-commentator Zoller at SeeMarthaSayIt.com.
