Massachusetts Voters Cast Their Ballots On Primary Day

The polls are open in Massachusetts — one of 13 states voting in Super Tuesday presidential primaries and caucuses across the country. In all, 865 delegates at stake for the Democrats, while Republicans are competing for 595.

Here in Massachusetts, there's a tight race between the two Democrats, Hillary Clinton and Bernie Sanders. And, in the GOP contest, Donald Trump has been leading in polls, raising the question — if Massachusetts Republicans won't stop his march toward the Republican presidential nomination, will anybody?

We spend the hour looking at Super Tuesday — here in Massachusetts and beyond.
