Unless you've been locked in a basement in Austria, you probably already know that North Carolina and Indiana Democrats are voting on Tuesday.

Here's an update from the campaign trail as Hillary Clinton and Barack Obama battle for delegates out west and down south.

In Indiana:
Early exit polls show that 'hardcore' democrats are crossing over to vote in the Democratic primary following a cry by Republican strategists and commentators to drag the primary on a bit longer.

Going into the day, most polls show that Clinton leads Obama. This state could give either candidate a much needed surge moving towards the Democratic National Convention later this summer.

In North Carolina:
Obama leads most polls going into election day in North Carolina, so a win for Hillary in that state would definitely send out a strong message to super delegates and those few states remaining to vote.

If Clinton upsets Obama in North Carolina, former President Bill Clinton can probably take some of the credit. He spent a lot of time talking to small time country folk who love it when he turns on the "Bubba."

There are 187 delegates up for grabs today — the largest delegate pool left in what has become a drawn-out Democratic primary battle.

Clinton is planning a victory rally tonight at a hotel ballroom in Indianapolis and Obama is planning a rally at a coliseum in Raleigh, N.C. That could be an early sign of where candidates think they will pick up the biggest wins.
