The ultimate guide to Super Tuesday

Should Trump win the GOP nomination, Alabama is set to be one of his strongest states in the general election. The former president easily carried the state in both 2016 and 2020, and with an evangelical base that remains strongly behind him, he's poised for a major victory over Haley.

Biden — who has sought to appeal to Black voters ahead of November — won over 70% of the Black vote en route to a huge victory over Vermont Sen. Bernie Sanders in the state's 2020 Democratic primary. That year, Black voters made up a near-majority of the Democratic primary electorate in Alabama.

While the state will almost certainly be in Trump's column in the fall, Biden's margins among Black voters could be a barometer of the current state of his campaign, as he'll need to energize this critical group across the country to secure reelection.

Alaska will hold a Republican caucus on Super Tuesday, which Trump is expected to win.

Despite Trump's popularity among the state's conservative base, his endorsement didn't help Kelly Tshibaka defeat GOP Sen. Lisa Murkowski in 2022. Murkowski, who voted to convict Trump for "incitement of insurrection" for his actions on January 6, 2021, recently threw her support behind Haley's presidential campaign.

Democrats will hold their presidential primary in Alaska on April 6.

Arkansas is another conservative-leaning Southern state that is almost certain to back Trump by wide margins in both the GOP primary and the general election.

Biden is expected to win the Democratic primary in the Natural State.

GOP delegates at stake: 169

California, the most populous state in the US, has the highest number of delegates in both the Democratic and GOP primaries.

Last year, the California Republican Party tweaked the rules for the primary, which will now afford all of the state's GOP delegates to the candidate who wins the contest with over 50% of the vote, in a move that's viewed as a boost to Trump. If no candidate wins a majority of the vote, then the delegates will be granted proportionally.

Biden is expected to win California's primary rather handily, but both Phillips and Williamson could chip away at his margins in this large state.

Both Biden and Trump are favored to win their respective primaries in Colorado.

In a 4-3 decision late last year, the Colorado Supreme Court ruled that Trump should be disqualified from appearing on the state's primary ballot, but the decision was stayed as the Trump campaign later sought an appeal.

On March 4, a day before Super Tuesday, the US Supreme Court unanimously ruled that states cannot disqualify Trump from the ballot.

Once reliably Republican, Colorado has voted for every Democratic presidential nominee since 2008. With its sizable share of college-educated suburban voters and unaffiliated voters, Haley could put up a solid showing in the state's GOP primary.

Republicans in the Hawkeye State held their first-in-the-nation caucus in January.

But after the Democratic National Committee moved South Carolina to the front of the line in the party's nominating process, Iowa Democrats instead turned to a presidential-preference vote via mail. (Voting began on January 12 and preference cards that are postmarked no later than March 5 will be accepted.)

In recent election cycles, Iowa, once a decidedly purple state, has shifted to the right, giving Democrats little hope that Biden can win the state this fall.

Trump carried Iowa in both the 2016 and 2020 general elections.

In Maine, both Biden and Trump are favored in their respective party primaries.

However, Haley is poised to peel off center-right Republicans who remain uncomfortable with a second Trump presidency, especially after Maine Sen. Susan Collins endorsed Haley's campaign last week.

Biden's victory in the 2020 Massachusetts Democratic primary effectively ended Sen. Elizabeth Warren's presidential campaign that year.

He's set to win the state's Democratic primary again, this time as the occupant of the Oval Office.

Haley could put up one of her best Super Tuesday showings in Massachusetts, as many of its GOP voters continue to embrace the sort of old-school Republicanism in the mold of former moderate Govs. Bill Weld and Charlie Baker. Still, Trump remains popular with base conservatives in the state.

In the general election, Massachusetts will lean heavily toward Biden.

Biden is expected to win Minnesota despite the presence of Phillips — a congressman representing part of the Minneapolis suburbs — in the presidential race.

Haley could attract the support of many of the state's suburban voters in the GOP primary.

North Carolina is poised to be one of the most competitive states in this year's general election.

Trump won the swing state in both 2016 and 2020, but the Biden campaign is desperate to flip it in November.

The primary results could reveal any major weaknesses and strengths for both Biden and Trump, especially in the populous suburbs surrounding Charlotte and Raleigh.

Both Trump and Biden are poised to win Oklahoma in their respective primaries.

Trump's conservative base is firmly behind him in Tennessee, while Biden should perform well with core Democratic constituencies in the state.

Trump has cultivated his political support in Texas for years, and even with the state's vast contingent of suburban voters, he's set to perform well there against Haley in the primary — especially with immigration being a paramount concern for GOP voters. The former president has long campaigned on border security and he's heavily amplified the issue ahead of a likely rematch with Biden.

In Utah, one of the most conservative states in the country, Democrats are holding a presidential primary while Republicans opted for a caucus.

On Super Tuesday, Haley could win some support from centrist Vermont Republicans who are leery of Trump. In January, the former South Carolina governor was endorsed by the popular GOP Gov. Phil Scott.

However, Vermont is a strongly Democratic state on the presidential level.

Both Biden and Trump are poised to win Virginia, which leans Democratic in presidential elections.

But Haley could make things interesting on the GOP side in Northern Virginia and in politically competitive suburbs and exurbs in metropolitan Richmond and Hampton Roads.

Democrats will hold caucuses in the US territory of American Samoa.  Republicans will hold their caucuses there on Friday after Super Tuesday.

While American Samoa doesn't have any electoral votes in the general election, it still plays a role in the nomination process.
