Former Vice President Joe Biden — taking his once-moribund campaign off life support — surged with strong wins in Super Tuesday voting, including an upset victory in Massachusetts.

Biden won broadly despite having far fewer resources than Bernie Sanders nationwide, picking up victories in states like Minnesota, North Carolina and Virginia, where the Vermont senator had campaigned over the past week.

And Biden surged in Massachusetts, overpowering Sanders, who held rallies in Boston and Springfield. He also blew past home-state U.S. Sen. Elizabeth Warren, who fell to third.

“It’s a good night! It’s a good night! And it seems to be getting even better,” Biden said from Los Angeles before polls closed in California. “They don’t call it Super Tuesday for nothing!”

A couple of dairy industry protesters rushed on stage — but Biden plowed on.

“Our campaign reflects the diversity of this party and this nation, and that’s how it should be, because we need to bring everyone along,” Biden said.

Biden Northeast Communications Director Emma Riley said, “Massachusetts sent a message to the rest of the country: This is the campaign that will send Donald Trump packing.”

On the Republican side, President Trump blew away former Massachusetts Gov. Bill Weld in the Bay State by a 75-point margin, MassGOP said in a Tuesday night release.

“Tonight, Massachusetts Republicans embraced Donald Trump, and those who would splinter and divide the Republican Party have fallen flat once again,” said Massachusetts Republican Party Chairman Jim Lyons.

A total of 1,344 delegates were up for grabs on the Democratic side in Super Tuesday voting in 14 states from Maine to California and Texas.

Biden’s wins in heavily African American states complemented the former vice president’s victory in last weekend’s South Carolina primary. Virginia was especially key because Sanders and billionaire former New York Mayor Mike Bloomberg heavily contested it over the past week.

A once-jumbled race arrived at the most pivotal night of the primary as an increasingly well-defined battle between leftist Democrats who back the likes of Sanders and Warren and centrists preferring Biden. A wild card was Bloomberg, who skipped the primary’s first four states but poured more than $500 million of his personal fortune into TV advertising in Super Tuesday states and faced increasing pressure to prove it was all worth it.

Some good news for Bloomberg came in the U.S. territory of American Samoa, where he took five of its six delegates. The final one went to U.S. Rep. Tulsi Gabbard of Hawaii.

At a Sanders supporters’ watch party at Democracy Brewing in downtown Boston Tuesday night, Bernie backers said the Vermont senator had the best chance against Trump in November.

“Here’s a guy who’s been consistently standing up for the same values and priorities for at least 40 years,” said Jesse Clingan, 42, who’s also a Somerville city councilor. “The other candidates have a lot of baggage, and have made changes in their politics through the years. Bernie is speaking the language of the working class, and I think he has the strongest chance of taking on Trump.”

The Biden and Sanders camps began ramping up attacks on each other Tuesday, each team sending out fundraising missives blasting the other as it increasingly looked like they would emerge the two leaders after Super Tuesday.

After U.S. Sen. Amy Klobuchar and former South Bend, Ind., Mayor Pete Buttigieg dropped out and quickly backed Biden, pressure mounted on Bloomberg to do the same.

But Bloomberg campaign manager Kevin Sheekey said as polls began to close that his candidate would “absolutely not” drop out Tuesday. According to multiple reports, Bloomberg is expected to reassess his campaign tomorrow.
