(NewsNation) — California is among the U.S. states holding its primary elections on Super Tuesday, the day with the most delegates up for grabs in the presidential race.

Voters in the nation’s most populous state will have their say in which candidates snag a presidential nomination. Republican voters will choose between front-runner former President Donald Trump and his opponent, former South Carolina Gov. Nikki Haley. Meanwhile, President Joe Biden remains the leading Democratic candidate despite losing some popularity among Michigan voters over his handling of the Israel-Hamas war. Trailing behind Biden are Democratic challengers Marianne Williamson and Minnesota Rep. Dean Phillips, who are also vying for the presidency.

Polls in California close at 8 p.m. PT. You can track the 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.

California voters will also weigh in on a Senate race between Rep. Adam Schiff, Republican candidate Steve Garvey, Rep. Katie Porter and Rep. Barbara Lee. Each hopes to secure the seat left vacant by the late Sen. Dianne Feinstein. There are two primary elections on the ballot to replace Feinstein: One to carry out the remaining months of her term and the other for a new six-year term starting in January 2025.
