Mitt Romney is joining the fight when it comes to 2010 campaigns; more evidence that Sen. Bob Bennett (R-Utah) is in some serious trouble; and a poll that probably isn't encouraging to potential Sen. Patty Murray (D-Wash.) challenger Dino Rossi.

Palin not the only prez hopeful on the trail

As Sarah Palin rallies the crowd for Sen. John McCain (R-Ariz.) today and supports challengers in three key Arizona House contests, Mitt Romney is getting a piece of the action too.

Romney has announced endorsements of Rep. Roy Blunt (R-Mo.) in his Senate campaign, as well as three House incumbents running for reelection and Rep. Russ Carnahan (D-Mo.) challenger Ed Martin. Earlier this week, he endorsed Rep. Jean Schmidt (R-Ohio), former Rep. Steve Chabot (R-Ohio) and Rep. Mary Jo Kilroy (D-Ohio) challenger Steve Stivers.

All House candidates got $2,500 check for their primaries from Romney’s Free and Strong America PAC, and Blunt got $5,000.

Bennett in trouble (update No. 85)

Sen. Bob Bennett (R-Utah) sounds like a man who knows he might be licked. He got the New York Times treatment today, and the result is telling.

Bennett acknowledged to the Times that, in his internal polling, he trails both "anyone-but-Bennett" and "undecided." Not sure if we've ever heard of an incumbent trailing "undecided" in a poll.

“If the anti-incumbent tide is as strong as some people think it is, I will be swept out, despite all my efforts,” Bennett said. “If the anti-incumbent tide is a lot of conversation, but has no center of gravity as a true political movement, then I’ll be just fine. There’s no way to know."

Of course, most indications are that the anti-incumbent sentiment is real. And we’ll say it again: if that’s the case, then an activist-driven process, which Bennett faces at May's state convention, is the last kind of process you want to go through.

The other Sen. Bennet -- Michael from Colorado -- saw it when he lost his state's precinct caucuses recently, and Bennett sounds like he has a bad feeling about his own fate.

Rossi down 11

Potential Washington Senate candidate Dino Rossi told The Hill recently that he wasn’t apt to run a race that would be decided by the narrowest of margins. He’s been there before, and it wasn’t fun.

But if a new Research 2000 poll for the liberal website Daily Kos is any indication, Rossi would be faced with just such a race, if he's going to be competitive at all.

While other polls have shown the two-time GOP governor nominee neck and neck with Sen. Patty Murray (D-Wash.), the latest has him trailing her 52-41.

Rossi was in Washington this week meeting with the NRSC. The timing of this poll isn’t ideal for the committee’s recruiting efforts, but Rossi has made it clear that he’s willing to wait as long as June to make his decision. We should have plenty more data to look at by then. The fact that he was in Washington is a good sign for Republicans.
