Sen. Blanche Lincoln (D-Ark.) issues an "ultimatum" to Lt. Gov. Bill Halter (D), Washington state Republican Dino Rossi's entrance into the GOP Senate primary doesn't clear the field and Newt Gingrich is still putting his money on a Speaker John Boehner (R-Ohio).

Lincoln: Come clean, Bill

Lincoln's refusal to support the Employee Free Choice Act (EFCA) was one of the issues that prompted labor groups to back Halter's primary bid. "My stand on this legislation is the reason D.C. unions are in Arkansas spending nearly $10 million attacking me and misrepresenting my record," Lincoln said in a statement Wednesday.

Before she agrees to another debate with Halter before the June 8 runoff, Lincoln wants her opponent to say definitively whether he supports the legislation. "Arkansans know my record, and they deserve to know where Bill stands. If we are going to debate the issues, we both have to be willing to take a stand on the issues," she said.

The Halter camp called the tactic "typical Washington hypocrisy."

Halter spokesman Garry Hoffmann: "This is exactly why we need to have a debate and exactly why she’s trying to avoid one."

Everyone's accounted for

At least five active Washington state GOP Senate candidates said they'll stick in the race after Rossi's entry, including former NFL player Clint Didier (R).

In fact, shortly after Rossi's Web rollout, the Sarah Palin-backed Didier hit him for being a party insider. Voters will now have a choice between a "GOP established candidate or a citizen statesman who is a part of the grassroots movement," Didier said in a statement published by the Spokane Spokesman-Review.

One candidate decided to get out. Ed Torres (R), a general superintendent for a plumbing firm, said he would put his support behind Rossi.

What are the odds?

Gingrich told reporters in Des Moines on Wednesday that Republicans still have a "great chance" to regain control of the House.

"I think the odds are at least even money that you're going to get John Boehner as Speaker," Gingrich said, according to the Des Moines Register. "The Democrats are going to run this fall with the worst unemployment record since the Great Depression, they're going to run this fall having failed in the Gulf, having failed to control the border, having failed to stop Iran and having failed to keep spending under control."
