(NewsNation) — Decision Desk HQ projects Democratic incumbent President Joe Biden and former President Donald Trump the winners of their respective primaries in Massachusetts.

Voters in Massachusetts were among those in more than a dozen other states who headed to the polls on Super Tuesday to weigh in on their preferred pick for the Republican and Democratic presidential nominations in the 2024 general election.

Republican voters will choose between front-runner Trump and his challenger, former South Carolina Gov. Nikki Haley. Trump entered Tuesday boosted by a major last-minute win from the U.S. Supreme Court decision Monday that said Colorado — and by extension, other states — could not exclude him from the ballot based on the 14th Amendment.

Meanwhile, Biden doesn’t face a formidable opponent, but his support took a hit in Michigan from frustrated voters who did not agree with his handling of the Israel-Hamas conflict. Advocates in other states are also pushing for voters to choose “uncommitted” as their selection on the ballot Tuesday.

Polls in Massachusetts close at 8 p.m. ET. You can track results of Tuesday’s primary election in the trackers below as results come in:

Heading into Tuesday, the former president has 221 delegates, while Haley has 43. On Tuesday, 865 GOP delegates and 1,420 Democratic delegates will be up for grabs, and you can track each candidate’s numbers in our tracker here. To clinch the nomination, Trump will need 1,215 delegates of the 2,429 available, so he will not win outright Tuesday, though success on the night will mean he’s much closer to the goal. The Massachusetts Republican presidential primary will also use a “winner-take-all” model which would give all 40 delegates of the state to the candidate who gets more than 50% of the vote.

The most competitive races in Massachusetts Tuesday may actually be local Republican and Democrat State Committee races. The more conservative, Trump-aligned faction of the Massachusetts GOP is running a “Freedom Slate” of state committee candidates to try and seize back power from first-term party chairperson Amy Carnevale. In 2021, Carnevale edged out incumbent Jim Lyons for the seat by the slimmest of margins, besting him by just 3 votes.
