State Sen. Cynthia Davis?

Dave Drebes reports that Rep. Cynthia Davis (R-O'Fallon) is expected to will challenge state Sen. Scott Rupp (R-Wentzville) next fall in the 2nd District GOP primary.

UPDATE: The Post-Dispatch has more:

“I guess the best way to describe this race is I’m more like Sarah Palin and he’s more like John McCain,” Davis said, referring to the 2008 GOP national ticket.

She said “the facts are the Senate needs me.”  Among other things, she said, she would be a strong anti-abortion advocate in the Senate.

“Nobody in the Senate is a true champion” on the issue, she said.
