NEW YORK (AP) – President Joe Biden and his likely Republican challenger, Donald Trump, are on track to win enough delegates this week to become their parties’ presumptive nominees.

Elections in four states on Tuesday will likely give Biden and Trump the delegates they need to clinch the nominations. 

But for many voters who aren’t attuned to the daily twists and turns of the nation’s turbulent politics, this week could be a crystalizing moment, reinforcing that another Biden-Trump campaign is virtually guaranteed whether Americans want it or not. And that rematch – the first in a U.S. presidential election since 1956 – is poised to deepen political and cultural divides.

Here’s what we’re watching:

WILL TRUMP CLINCH?

Tuesday should be a wakeup call for those who still doubt that Trump, who is facing 91 felony counts in four criminal cases, will represent the Republican Party in the general election this fall.

The former president is on track to win enough delegates to become the Republican Party’s presumptive presidential nominee – if he continues to dominate the way he has throughout the primary season. And with no major opposition on the ballot, there is every reason to believe he will.

As of Sunday, Trump was 140 delegates short of the 1,215 needed to win the Republican nomination at the party’s national convention this summer. There are 161 Republican delegates at stake on Tuesday in Georgia, Mississippi, Washington state and Hawaii.

With a strong showing on Tuesday, Trump can sweep all the delegates in Georgia, Mississippi and Washington state. Hawaii allocates delegates proportionally so other candidates could win a few, even with a small share of the vote.

WHAT ABOUT BIDEN?

Like Trump, Biden is on the verge of securing sufficient delegates to become the Democratic Party’s presumptive presidential nominee.

The president enters Tuesday 102 delegates short of the 1,968 needed to win the Democratic nomination. There are 254 Democratic delegates at stake delegates at stake Tuesday in Georgia, Mississippi and Washington state, in addition to party-run contests for the Northern Mariana Islands and Democrats Abroad that conclude that day.

With no major opponents, Biden is on pace to reach that mark. But he’s also facing continued resistance from his party’s left flank that threatens to tarnish the achievement.

A collection of progressive activists and faith leaders in Georgia and other states are encouraging Democratic primary participants not to vote for any presidential candidate. That’s after a protest “uncommitted” vote in Michigan recently secured two delegates.

The symbolic protest is meant as a warning on Biden’s reelection over his support for Israel’s war against Hamas in Gaza.

While Biden’s campaign says it’s not worried, the president must unite his party behind him if he hopes to defeat Trump in November.

GEORGIA PREVIEW

Georgia has emerged as one of the nation’s premier swing states in recent years. And both candidates are eager to put up a strong showing and flex their organizational muscle in what is effectively a dress rehearsal for November’s far more consequential general election.

The state was a pivotal battleground in 2020 – so close that Trump finds himself indicted here for his push to “find 11,780 votes” and overturn Biden’s victory.

Both candidates made Georgia a priority in the days leading up to Tuesday’s primary. But they offered very different messages in dueling rallies over the weekend.

Trump’s Saturday rally opened with a message asking attendees to support the people serving jail time for their roles in the Jan. 6 Capitol insurrection. The former president then appeared with MAGA firebrand Rep. Marjorie Taylor Greene, R-Ga., whom he called “brave” for yelling at Biden during his State of the Union address. Trump also highlighted his private meeting the night before with Hungarian Prime Minister Viktor Orbán, who has rolled back democracy in his country.

Biden, working to energize his coalition of voters of color, young people and suburbanites, pointed to Trump’s controversial associates and his embrace of the far right. “Our freedoms are literally on the ballot this November,” he said.
