CQ Politics has changed its rating for the race between GOP Rep. Dave Reichert and Dem Darcy Burner from "Leans Republcian" to "No Clear Favorite":

Democrat Darcy Burner’s challenge to freshman Republican Rep. Dave Reichert in Washington’s 8th District has become one of the year’s key battleground races -- as evidenced by the fact that the national parties poured nearly $1 million dollars into this contest in the last two weeks...

Independent polls indicate that Burner, a former Microsoft executive making her first bid for public office, is gaining ground in this partisan swing district in suburban Seattle.

Reichert has positioned himself as a moderate from the beginning of his tenure, but recently boldly underlined his reputation as a “centrist” in his releases...

The National Republican Congressional Committee -- the GOP’s national House campaign unit — spent at least $728,000 from Sept. 29 through Oct. 9 on an independent expenditure campaign opposing Burner.
