In his bid to upset Hillary Clinton in the race for the Democratic presidential nomination, Vermont Sen. Bernie Sanders had high hopes for a win in Massachusetts.

But the last thing he should have expected was for the Clintons to play fair.

One day after Clinton eked out an incredibly narrow Super Tuesday win in Massachusetts (50.3% to 48.6%), Sanders supporters were accusing the Clintons of election fraud and saying victory in the state may have been stolen.

Video has surfaced of Clinton’s husband, former President Bill Clinton, appearing at a New Bedford, MA polling station and with the help of the mayor, the videographer alleges, blocking Sanders supporters from entering and voting. New Bedford was considered a toss-up area of the state, with lots of support for Sanders.

That wasn’t the only accusation of election fraud that emerged from the Bay State.

Voters complained that earlier, Slick Willy had been actively campaigning inside polling areas around the state, pressuring citizens to support his wife in clear violation of voting laws.

“We received some complaints that he was campaigning, and the office reminded the campaign that state law prohibits campaigning within 150 feet of a polling place,” Brian McNiff, spokesman for Secretary of the Commonwealth, William F. Galvin, told the Boston Herald.

In all, Clinton won Alabama, Tennessee, Georgia, Virginia, Texas, Massachusetts and Arkansas, her former home state.

Which states she won fairly may be another matter for discussion.
