State Sen. Renee Unterman has yet to enter the 7th District congressional race, but she's already taking swipes at one of her likely opponents.

And her Twitter attacks served as a preview of how bitterly-fought the contest to succeed retiring Republican Rob Woodall could be.

The Buford Republican took a shot Wednesday at GOP candidate Lynne Homrich, who moved to the district from north Atlanta shortly before announcing her campaign.

“Clue #1, your DC consultant’s mistake, Gwinnett/Forsyth counties are suburbs ... we are not ATLANTA! Maybe you all should come out & visit families to find out where you are suppose to campaign in #7thdistrict; you might even like it, big contrast from #Buckhead #fakecampaign,” Unterman tweeted.

The comment came in response to a Homrich campaign post about the former Home Depot executive’s economic platform.

“When businesses are over-taxed and regulated, Atlanta families lose,” stated Homrich’s original tweet.

Homrich has been the talk of Georgia Republicans since her out-of-left-field campaign announcement last week. She has a veteran campaign consultant, deep pockets and business background - all key factors for a successful outsider bid.

Unterman and her allies say they’re unfazed. On GPB’s “Political Rewind,” Unterman adviser Todd Rehm said the state senator will likely enter the race before the June 30 quarterly deadline.

He said she seemed newly-energized to “go out there and climb a mountain” and run for another office after the last legislative session, where she was demoted from a key committee post.

This isn’t the first time Unterman has gone after Homrich.

Two days after Homrich announced her 7th District bid, Unterman tweeted about “that Buckhead lady” who “might need some directions” to Cumming and Lawrenceville.

The two will have company in the GOP primary. Former Atlanta Falcons running back Joe Profit has already joined the field, and several other well-connected Republicans are also considering bids.

Five Democrats are also vying for their party’s nomination.
