INDIANAPOLIS -- In Indiana and North Carolina, 187 delegates are up for grabs.
Barack Obama and Hillary Clinton have been going back between the two states courting voters and telling them why they should vote for them.
Polls have shown Clinton chipping away at Obama's advantage in North Carolina, though they suggest a much tighter race in Indiana.
Both candidates have predicted the race will continue until the final contests in Montana and South Dakota next month, and both candidates have bee campaigning hard.
"I want your vote. I want it badly," Obama said to a crowd.
"God bless America," his opponent, Clinton, said.
Clinton and Obama have been campaigning like crazy -- hitting the town hall meetings and the rallies with messages for voters as they head to the polls.
"There isn't anything we can't do if we start acting like Americans again -- if we roll up our sleeves, if we set some big goals and we start achieving them. That's who we are," Clinton told supporters.
"I don't buy into this electability argument. Go with who you think best, represents your vision of where America needs to go, and if you do that, I'm absolutely confident that that person will win," Obama said.
In appealing to middle class America, blue collar workers and families, both candidates are promising a lot.
I will never forget you. I will get up every single day in that White House. I will work to make your lives better," Clinton said.
But only voters can choose who will be victorious after the polls have closed.
"The fact that were still standing here, and still moving forward towards the nomination, I think, indicates the degree to which the core message of this campaign is the right one," Obama said.
Unlike the Democrats, John McCain doesn't have to feel nervous Tuesday. The presumptive Republican nominee can keep campaigning with an eye on the general election.
