Super Tuesday is tomorrow. Here's what to expect

Voters in 16 states and one territory will make their voices heard Tuesday in the biggest primary election of the 2024 cycle. Also known as "Super Tuesday," this is the biggest single primary contest day, resulting in over a third of delegates assigned to determine the GOP presidential nominee.

As a result, this is effectively former U.N. Ambassador Nikki Haley's last shot to slow former President Donald Trump's path towards nomination. Ahead of the mammoth election night, Haley's campaign launched a seven-figure national cable and digital ad buy to run through at least Tuesday in hopes of winning over voters. Her campaign has also been criss-crossing the country in the final days ahead of March 5 to meet as many voters as possible.

Trump will be entering the week coming off of wins in Haley's home state of South Carolina, winning 60% of the vote, and Michigan, where he secured 70% of the vote. While Trump does lead on delegate count and votes, having won every primary thus far, Haley is still securing a third of voters, which could be an eventual concern for Trump in what's shaping up to be a general election rematch with President Biden on Nov. 5.

Super Tuesday is not the end of the primary season. The remaining states will vote through the summer and fall on their primary slates. Republicans will gather in July in Milwaukee for their convention to officially nominate the GOP candidate for the general election and Democrats will gather in Chicago in August to select their candidate.
