Jim Marshall will probably win his primary, despite a challenge from the left:

The few Robert Nowak campaign signs explain why a Vermont cellist-turned-Bibb County elementary school teacher would take on a three-term incumbent for a seat in Congress.

"Nowak," the signs announce. "A True Democrat."

After years of making sure his conservative streak beat back the liberal tag Republican opponents tried to hang on him, U.S. Rep. Jim Marshall has earned a primary opponent who says he's not liberal enough.

"Mr. Marshall's not far from (Republican challenger Rick) Goddard," Nowak said. "I want to give Democrats a choice, I guess. ... No one was doing it. If somebody else had done it, that would be fine."
[...]
Nowak favors health care for "all needy children" through an expansion of the State Children's Health Insurance Program, called SCHIP nationally and PeachCare in Georgia. Marshall voted against an expansion of this program last year, drawing criticism from Democrats who, like Nowak, have grown tired of some of Marshall's more conservative votes.

You know, I thought about voting in the Democratic Party primary for awhile (that would have been a first), but I'll vote in the GOP primary to support a couple of candidates on the local and state levels. However, I cannot bring myself to vote for Rick Goddard. I'll be voting for Marshall in November.
