NEW BEDFORD — Former President Bill Clinton stopped by the Buttonwood Park Warming House in New Bedford today to campaign for his wife and presidential candidate, Hillary Clinton.

Mayor Jon Mitchell also was at the event.

Earlier, Clinton stopped by the Friedman School in Taunton. State Sen. Marc Pacheco, D-Taunton, who helped open a Hillary Clinton campaign office in Taunton last week, was at the event, along with Taunton Mayor Tom Hoye and Superintendent of Schools Julie Hackett.

Bill Clinton was in Newton this morning, too.

Democrats Hillary Clinton and Bernie Sanders are locked in a close race in today's primary as they try to secure their party's nomination.

While Clinton has much of the Democratic establishment behind her, Sanders is banking on strong support from the state's college-age voters to help keep his candidacy afloat.

Republican voters will choose between the five remaining candidates — Donald Trump, Marco Rubio, Ted Cruz, John Kasich and Ben Carson.

Although Trump has held a solid lead in most polls, Kasich is hoping for a strong second place finish.

Today's primaries are as much about rounding up delegates as winning individual states.

Most polling locations in Massachusetts are open from 7 a.m. to 8 p.m.
