Speculation Central: Senate District 32

Now that the legislature is in recess, we'll start hearing immediately about many of the impending 2008 House and Senate races across the state. One race that's already generating a lot of discussion is Senate District 32, which will be vacated by Sen. Jim Argue due to term limits. This district includes most of west Little Rock, Cammack, Hillcrest (most of it), the Heights, and Leawood. These'll be some big shoes to fill. I've heard that Rep. David Johnson is interested, and Rep. Sid Rosenbaum could be considering it as well. Who else? What's the word?
