From the Journal:
Across the state, Democrats are penciling in Wes Shoemyer to win the 18th district, the northeast corner of Missouri. A former state representative who's being term-limited out, he's in a heavy fund-raising battle with Republican Bob Behnen. Finally, Doug Harpool in the 30th district, running against Norma Champion in Springfield, [Matt] Blunt's back yard, is considered a possible pick-up.
The 30th District seat was the most competitive state senate race in Missouri in 2002. There is every reason to believe it will be just as tight this year.
