Chambliss was one of a majority of Republican senators to vote earlier this week for the "fiscal cliff" bill, which sought to avoid tax increases and budget cuts. Kremer expressed frustration that he wasn't conservative enough.
"The Tea Party Express, we haven't decided anything at this point, but I can tell you I live in the state of Georgia and Saxby Chambliss is going to be primaried. Our own senator. It's unacceptable to have somebody who votes with the Democrats more than they do with the conservatives, and he has proven time and time again he's all about the spending," she said.
"And we're a red state, we deserve a conservative senator, a conservative senator that would stand with [Sens.] Marco Rubio [R-Fla.] and Rand Paul [R-Ky.] and Mike Lee [R-Utah] who all voted 'no' for this bill," she added.
Chambliss has stoked the ire of the GOP grassroots in Georgia for his bipartisan work on issues ranging from immigration to reducing the debt, and he's expected to face a primary challenger, but no candidate has yet announced an official bid.
