With only hours remaining until the May 6 primary election, the campaigns to elect Hillary Clinton and Barack Obama are making their final pushes through the Tar Heel state.

With each stop hoping to shift the tides a percentage point in the Democratic race for president, and with each speech attempting to inspire the electorate to come out to vote on Tuesday – the candidates are pulling out all the stops.

But Clinton and Obama are running low on time in North Carolina.

Each candidate has increased the number of TV ads being run, campaign representatives said, and each campaign is sending an average of 10 e-mails per day to media outlets and supporters throughout the state.

During the last few weeks, both candidates have made more than a dozen appearances in North Carolina, generally unheard of in a state whose primary lands so late in the game. Both Clinton and Obama, along with their top surrogates, are swinging through the state today, as well.

Clinton is speaking today at 8:30 a.m. at Pitt Community College in Winterville and later in High Point.

Meanwhile, her husband, Bill Clinton, is in the midst of a 15-town swing

through rural North Carolina, bringing the former president as close to the Twin Counties as Zebulon.

Bill Clinton has appeared at events in several smaller, more rural towns throughout the state in recent months, including an April appearance at N.C. Wesleyan College in Rocky Mount. Hillary Clinton, on the other hand, has focused her efforts in larger cities, speaking to more robust crowds.

Obama, in addition to speaking in Wilson last week, has appeared in Greenville and numerous other cities throughout the state. He'll meet today at 12:45 p.m. with middle-class workers in Durham.

Obama's wife, Michelle, is spending today promoting her husband's case to become the next president during stops in Fayetteville and Charlotte.

"It's great how much attention we've gotten lately," Steph Price said at the Barack Obama rally in Wilson last week. "For the first time as long as I can remember, we are getting to see and hear from these candidates in person."

Attention-starved voters should relish the opportunity to hear from the presidential candidates while they still have the chance.

It's unclear if the U.S. senator from New York and Illinois will make any other appearances in North Carolina before or during Tuesday's election.

Regardless, most of the 30-plus local Obama campaign headquarters throughout the state have get-out-the-vote events planned both today and Tuesday.

Scores of Clinton volunteers likely will be doing the same.

"It's crunch time," local Obama volunteer Bruce Williams said last week. "We have to do everything we can to win voters."

Because May 6 is less than a day away.

And the clock is ticking in North Carolina.
