Former President Bill Clinton is getting the rock star treatment as he stumps for his wife, former secretary of state Hillary Clinton, in the Massachusetts presidential primary.

Hillary Clinton and fellow Democratic candidate Bernie Sanders are close in the polls and in a statistical dead heat according to one.

The ex-president and Boston Mayor Marty Walsh appeared together at a polling place in the city's West Roxbury neighborhood early Tuesday, where they greeted voters and school children.

Walsh said the GOP candidates for president are "an embarrassment to the office" after voting for Hillary Clinton near his Dorchester home.

Polling places across the state opened at 7 a.m. and voters seemed eager to have their voices heard.

People had already started lining up at one polling place in the Boston suburb of Arlington even before polls opened.

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