So, what’s at stake?

The Republicans are voting in 11 states, with 595 delegates up for grabs. That’s about 25 percent of the total GOP delegates available nationwide.

Donald Trump – who is in Florida – is currently leading the GOP pack with 82 delegates. Sen. Ted Cruz has 17 delegates and Sen. Marco Rubio has 16. The Florida senator will be watching the “Super Tuesday” results from Miami where he is holding a rally.

Cruz is facing a big test in his home state of Texas. With 155 delegates, Texas is the biggest prize of any contest on Super Tuesday. This morning in Houston Cruz was quick to cast his ballot.

The Democrats are also voting in 11 states and American Samoa, with 865 delegates up for grabs.

Both Hillary Clinton and Sen. Bernie Sanders are almost guaranteed at least one state on Super Tuesday.

Sanders cast his Super Tuesday ballot in his home state of Vermont Tuesday morning chalking his nomination chances up to voter turnout.

“I am confident that if there is a large voter turnout today, across this country, we are gonna do well,” said Sanders.

While Sanders is expected to dominate in his home state of Vermont, Clinton is expected to win Arkansas, where she served as First Lady while her husband was governor.

Bill Clinton made a campaign stop at a polling station in Massachusetts while preparations were underway in South Florida for Hillary’s Super Tuesday event.

The latest polls show a big lead by Clinton who is expected to gain far more delegates than Sanders on Tuesday making it tough for him to catch up.

After Clinton’s decisive win in South Carolina, Clinton leads Sanders in delegates 91-62. But when super delegates are included, Clinton’s lead widens to 544-85.

It takes 2,383 delegates to win the Democratic nomination.

No one is expected to win a nomination on Super Tuesday but if the polls are accurate, Clinton could pick up enough delegates to make her unstoppable.
