Mitt Romney made it 5 contests in a row with a victory in the Washington state caucuses.

CNN:

Mitt Romney won the Republican caucuses in Washington state, according to unofficial results early Sunday, giving the former Massachusetts governor a shot in the arm heading into Super Tuesday contests.

With 99% of the vote in, Romney had 38%. Texas Rep. Ron Paul had 25% and former Pennsylvania Sen. Rick Santorum had 24%. They were trailed by former House Speaker Newt Gingrich at 10%.

At stake in the contest are 40 delegates.

"We're in a good second place, but the good news is we're doing very, very well in getting delegates," Paul told supporters in Seattle, when about half of the vote had been counted. "The enthusiasm for the cause of liberty continues to grow exponentially."

Washington's caucuses come just three days before Super Tuesday, when 10 states hold primaries and caucuses. And because of that, all four major GOP presidential candidates campaigned in the state, hoping a strong finish would carry over to Tuesday.

State GOP chairman Kirby Wilbur predicted a large turnout and estimated between 500 and 1,500 did not vote in Kennewick city because of overcrowding.

Once again, the "I" word is rearing its head with regard to Mitt Romney. But "inevitability" is still mostly hype at this point. Very soon, however - perhaps by the end of this month - Romney's lead in actual delegates chosen will be so large as to make any comeback by Santorum or the others a long, uphill slog.
