Down to the Wire: Will Voters Send a New Message on Super Tuesday?

It's Super Tuesday, the biggest voting day of the year leading up to the general election. So far, Donald Trump and Hillary Clinton are both leading their parties in national polls.

 But will voters in some states send a new message?
 
One quarter of Americans in a dozen states and a U.S. territory are going to the polls, with a combined 1,610 delegates on the line for both parties.

So what can we expect during tonight’s big Super Tuesday Primary Day? Watch David Brody's analysis:

A new CNN poll shows Trump has a commanding lead over all the other Republican candidates, with 49 percent to Marco Rubio's 16 percent and Ted Cruz's 15 percent. Dr. Ben Carson and Ohio Gov. John Kasich are trailing at 10 percent and 6 percent .

And Clinton is dominating Bernie Sanders in the Democratic race as well, with 55 percent to Sanders' 38 percent.

Clinton and Trump are looking to solidify their positions as the clear frontrunners for their parties' nominations. Meanwhile, Sanders, Rubio and Cruz are trying to remain alive.

"We are the only campaign that can beat Donald Trump," Cruz recently told supporters.

The Texas lawmaker is hoping to win decisively in his home state. Leading up to Tuesday's vote, he was out talking about religious liberty and the Supreme Court nomination

"Let me tell the men and women of Texas this: I will not compromise away your religious liberty rights," he vowed.

And the jabs between Trump and Rubio were still flying.

"We are not going to allow a con artist to take control of the party of Lincoln and Reagan," Rubio said.

Trump, in turn, took a shot at Rubio, saying, "In Florida, where he's from, he couldn't be elected dog catcher."

Meanwhile, there was trouble during a Trump appearance in Virginia, where a Time Magazine photographer and a Secret Service agent got into a scuffle.

And later, the business mogul didn't mince words when addressing a group of protesters who tried to disrupt the rally.

"Tens of thousands of people ... are you back there, darling? Who is protesting? Anybody? Get out of here.  Get them out. Get them out," he said.

Cruz has a good chance to claim both Texas and Arkansas, while Rubio might hang on to win Minnesota. But Trump seems to be in the lead everywhere else – including Rubio's home state of Florida, where early voting has already begun for the March 15 primary.

On the Democratic side, Clinton is looking to maintain her lead over Sanders.

"America is already great – make it whole again," Clinton said.

And Sanders drew applause from supporters when he declared, "We can win the Democratic nomination."

But that will only happen if Sanders can pull a rabbit out of the hat Tuesday.  A fundraising email from Clinton shows she's already looking past Sanders and targeting Trump.

Clinton, however, could still face problems after the State Department released her final batch of emails Monday, with 261 of them containing classified information.  Now the question is – will she face legal problems down the road for breaking the law?

And some think Trump could also take a hit if the New York Times releases an audio tape from an off the record meeting at the newspaper in January. The recording allegedly shows Trump doesn't believe what he's saying on immigration.
