The biggest night of the Presidential nominating process is just days away.
Voters will head to the polls on Tuesday in about a dozen states, for what's known as "Super Tuesday" - and there's a lot on the line.
Some analysts think Hillary Clinton and Donald Trump could essentially lock up the nomination in their respective parties if they sweep those states on Tuesday.
In the video above, UIndy political science professor Laura Albright breaks down the polling numbers for Super Tuesday, which show Clinton and Trump with large leads in most of the states voting Tuesday.
In recent days, a number of key Republicans have weighed in with critical endorsement ahead of Tuesday's vote. Trump landed a surprise endorsement from former Presidential candidate Gov. Chris Christie (R-NJ), and here in Indiana, Sen. Dan Coats (R-IN) threw his support behind Sen. Marco Rubio (R-FL).
"It's time for us to focus on who has the best chance to win and who's a major conservative, who has the background and talent to be able to win in the fall and as I evaluate this I think Marco Rubio is the person to do that," said Coats in a interview for this week's edition of IN Focus.
