There is more on the story about a possible challenge to Glenn Richardson. A few Republican members of the State House are publicly announcing their intent to support David Ralston for Speaker:

Rep. Tommy Benton and Rep. Terry England (Jackson & Barrow counties) are backing an effort to oust Rep. Glenn Richardson as speaker of the Georgia House of Representatives.

Benton, (R-Jefferson) and England (R-Winder) were among a handful of disgruntled legislators who were scheduled to announce support this week for Rep. David Ralston, Blue Ridge, in challenging Richardson, who is best known as the author of legislation attempting to replace property taxes throughout Georgia with an increased sales tax.

“I’m supporting Mr. Ralston,” said Benton by phone from Oklahoma, as he returned from a conference.

In addition to England, Benton listed Rep. Tim [Bearden], Carrollton; Rep. John Meadows, Calhoun; and Rep. Doug Collins, Gainesville, as other key supporters of the insurrection.

“I think we’ve got the votes,” he said. “If we are unsuccessful with this, you’ll probably see my office in the island of Nod somewhere with the others.”

“It had gotten to the point where we were becoming more and more isolated,” Benton said. “It is all right to be independent, but to continually do things to isolate the House ... there were some things that were done that a lot of us didn’t like. We just felt like it was time for a change.”

Like I wrote yesterday, I want to see Richardson out as much as anybody. I just don't think it'll happen. On the other hand, maybe there is something there for these guys to stick their necks out like this.
