Massachusetts has been pulled into the election-fraud controversy after President Trump — offering no evidence — claimed that thousands of Bay State voters were bused to New Hampshire to cast ballots last November.

In a closed-door meeting with 10 senators about Supreme Court nominee Neil Gorsuch, which also included former New Hampshire U.S. Sen. Kelly Ayotte, Trump insisted both he and Ayotte would have won the Granite State had it not been for the “thousands” of people “brought in on buses” from Massachusetts to “illegally” vote in New Hampshire, according to Politico.

Bay State Democrats last night dismissed Trump’s allegations as baseless nonsense.

“This is the latest in a seemingly endless stream of outlandish lies being peddled by the president,” said Gus Bickford, chairman of the Massachusetts Democratic Party. “Donald Trump lost New Hampshire fair and square and lost the popular vote nationally. He has presented no evidence to the contrary. He needs to get past his petty embarrassment and get serious about the job of the presidency.”

Trump lost New Hampshire to Hillary Clinton on Nov. 8 by a thin margin of 2,732 votes. The GOP’s Ayotte lost her Senate seat to Democrat Maggie Hassan by 743 votes.

But Trump’s hardly the first to raise such concerns, and many point to state rules that allow for same-day registration.

Former Massachusetts U.S. Sen. Scott Brown, who now lives in New Hampshire, has claimed the region’s prevalence of college students helps tilt elections.

“People from Massachusetts could have gone up and voted that day and quite frankly some do,” Brown told Boston Herald Radio in November after the election. “It’s well known. It’s no secret.”

New Hampshire Gov. Chris Sununu, then campaigning, told the Howie Carr Show a week before the election that Democrats had been busing Bay State residents into New Hampshire to vote: “There’s no doubt there’s election fraud here.”

New Hampshire state Rep. Al Baldasaro, a co-chairman on Trump’s campaign, said he saw more than two-dozen Massachusetts license plates at a polling location in Londonderry on Election Day. He concedes they could have been new residents to the state (and there’s no evidence they actually voted), but Baldasaro believes voter ID laws would be a step in the right direction.

“I saw more Massachusetts cars in my polls than I’ve ever seen in other elections,” said Baldasaro. “He’s right about the fraud in New Hampshire. We’re aware of it, big time.”

Former state Democratic Chairman Phil Johnston said people from Massachusetts went to the Granite State to help Clinton and Hassan — but they were knocking on doors and getting out the vote, not illegally casting votes.

“Of course there were a lot of people from Massachusetts who went to New Hampshire to help Maggie Hassan and Hillary, but the Republicans did the same around the country,” Johnston said. “It’s more insanity from Trump. People went to persuade New Hampshire voters to vote for Hillary. … It’s just another example of his alternative facts.”

Meanwhile, Politico also reported that during the same meeting, Trump repeatedly referred to Massachusetts Sen. Elizabeth Warren as “Pocahontas,” a reference to accusations that she claimed Cherokee heritage to advance her career as a law professor, and told Senate Democrats he was glad she was becoming the face of “your party.”

The comments were prompted by Warren’s rebuke on the Senate floor after trying to read a letter from Coretta Scott King in an attempt to defeat the nomination of former Alabama U.S. Sen. Jeff Sessions as Attorney General.
