Candidates clamor for last-minute votes

(NBC) - A flurry of last minute politicking is underway across the country and if the latest NBC News-Wall Street Journal poll is any indication, the country is in for another change.

He's not on the ballot, but President Obama pleaded with supporters at a rally in Cleveland Sunday.

"If everyone who fought for change in 2008 shows up to vote in 2010, we will win this election, I am confident of that," he said.

Heavy voter turnout may not be enough, though.

The NBC News-Wall Street Journal poll released Sunday shows nearly 50-percent of likely voters prefer a GOP-controlled Congress right now.

More telling, 63-percent say they want to see a great deal of change or quite a bit of change in the way the president has been leading the country.

"There's no question that this midterm election is a referendum on Obama's policies," Mississippi Governor Haley Barbour said.

Sarah Palin isn't on the ballot either, but was on the trail for conservatives over the weekend.

"I think it's going to be a political earthquake and the message will have been sent to the Left that they blew it," she told supporters.

Former President Bill Clinton weighed in for Democrats with a plea for patience.

"You gave them eight years to dig the hole. Give us four years, just half the time, to get out," he said.

Most analysts predict a big night for the Republicans with at least a 50-seat swing in the House and significant gains in the Senate.
