You knew it was coming.

Democratic U.S. Sen. Patty Murray has launched a new TV ad hitting Republican Dino Rossi for his conservative positions on abortion rights and related women's health issues.

The ad, called "Trust," dusts off some old votes Rossi took as a state legislator, such as his vote against requiring insurance companies to cover female contraceptives.

In an accompanying news release, Democrats also cited anti-abortion comments Rossi made early in his political career, when he talked more about he subject.

During his two runs for governor in 2004 and 2008, Democrats frequently accused Rossi of hiding the extent of his conservatism on such social issues.

They're resurrecting that argument now with ballots due to be mailed out shortly for the Nov. 2 election.

On Wednesday, Gov. Chris Gregoire plans a Seattle campaign appearance with Planned Parenthood Action Fund President Cecile Richards, to further hit Rossi's views on abortion rights.

Rossi has said he'd vote his conscience on subjects like abortion and gay marriage, but that they're not the reason he's running for office. He wants to keep the discussion centered on the economy, jobs and taxes.

Ironically, Rossi was attacked before the August primary by some anti-abortion activists for not being rigid enough in his views. (That's because he frequently has said he favors legal abortion in cases of rape and incest or when the life of the mother is threatened.)
