Sen. Hillary Clinton, D-NY, in her final swing across North Carolina before the primary vote there Tuesday continued to drive her three main points against her opponent, arguing her plans for health care, home foreclosure and suspending the federal gas tax during the summer months are better than her Democratic rival Sen. Barack Obama, D-Ill.

In a lighter moment, Clinton tried to appeal to North Carolinians in the town of High Point with a twinge of a southern accent speaking about BBQ.

On that topic Clinton said the only question she will not answer in this campaign is about which BBQ she prefers.

"We have had the best time. We have eaten BBQ from one end of this state to the other. You know for a while I was a little worried because every sighting of my husband was going into or going out of a BBQ joint. And I said, 'I hope his cardiologist doesn’t read that.' But then I kind of got into the swing of it too, and I said the only question I will not answer in this campaign is -- which is the best BBQ. I've made plenty of mistakes in my life, but I'm not walking into that one."

Clinton again criticized her opponent for not accepting her gas tax relief proposal saying, "Sen. Obama wants you to pay the gas tax this summer - instead of trying to get it so the oil companies pay it out of their record profit. I believe that we should start standing up for the vast majority of Americans who are paying these outrageous prices."

Clinton also said that as president, she would try to sue OPEC -- the Organization of Petroleum Exporting Countries, which controls the price of two-thirds of the world's oil supply.

"We're going to go after OPEC which remember is a monopoly cartel," Clinton said. "There's nothing free-market about it. They sit in some conference room a couple of times a year and decide how much oil they are going to produce and how much they are going to charge for it. So lets change our laws so we can sue them on anti-trust reasons."

Clinton also said her opponent doesn't cover everyone in his health care plan and also pointed out that they differ on their mortgage crisis relief plans. "This is a big difference between me and my opponent in this campaign. I have been saying for over a year we need to take on the Wall Street bankers and the mortgage bankers that misled so many people into these sub-prime mortgages."

After spending the morning in North Carolina, Clinton heads to Indiana, which is also voting Tuesday, where she will finish her day with several more campaign stops.

Meanwhile Obama toured Indiana and courted the white, blue collar crowd, dropping in on a construction site as workers filtered in on first shift with lunch pails and hard hats. Afterward, he hit the buffet at a labor union breakfast in Evansville, Indiana.

Obama spoke about his chances in the race that has tightened significantly over the past few weeks.

"I think our chances are good. I mean we've had a good week of campaigning," Obama said about his time spent in Indiana, "We're working as hard as we can and I desperately want every vote here in Indiana and in North Carolina."

In the last 24 hours leading up to election day, Obama and Clinton will be bouncing back and forth between North Carolina and Indiana.

"This is gonna be a tight election here in Indiana," Obama said at a labor union breakfast in Evansville, Indiana, where the Senator discussed his opposition to Clinton's gas tax relief proposal.

"It's a stunt, its what Washington does, this isn't the first time its been proposed, its proposed every two years," he said and suggested that a second stimulus check would be a better solution for short term relief.

"That would help people immediately relieve some crisis and that's money that you know wont be sopped up by oil companies."

"Those aren't just words 'cause I'm gonna be following through. But I need your help to get me there," Obama said and asked for the union members to help him get out the vote tomorrow.

The lanky Illinois senator moseyed over to the breakfast buffet table and noted that he'd lost some weight over his 15 month run, "I've been losing weight on this campaign. I hope there are some biscuits and grits."
