On Tuesday night, Donald J. Trump won another four nominating contests and officially became the presumptive Republican nominee. That’s despite the criminal charges, the judgments made against him in defamation and sexual abuse cases, the hundreds of millions of dollars in legal penalties and the continued fallout from the events of Jan. 6, 2021.

Considering all of that, we want to ask Republicans the same questions we posed to Democrats last week — and to answer them more directly than we have before:

How exactly did we end up with Donald Trump as the Republican nominee again? And why?

To answer these questions, we turn to two different branches of the Republican Party today.

First, we speak with Henry Barbour, who has been a member of the Republican National Committee since 2005, a consummate party insider. He supported Nikki Haley in the primary but now supports Mr. Trump. Then we speak with Vivek Ramaswamy, who ran against Mr. Trump for the nomination, but was most similar to the former president among the other candidates in terms of ideology and style. He now fully backs his one-time rival and embraces the MAGA philosophy he represents.

With Super Tuesday behind us, this week is the end of one chapter of this campaign.

On the Republican side, former President Donald Trump’s only remaining challenger, Nikki Haley, is out of the race. And on the Democratic side, President Biden has so far secured more than 70 percent of the delegates he needs to secure the nomination.

The general election is here. And so too is the rematch we’ve been expecting, despite the fact that the majority of Americans continue to say they wish they had other options.

So for the next two episodes, we’re going to focus on a question we hear more than anything else: How exactly did we wind up with these two candidates? And why?

First up: We map Mr. Biden’s path to the 2024 election through conversations with Elaine Kamarck, a longtime member of the Democratic National Committee and the author of “Primary Politics: Everything You Need to Know about How America Nominates Its Presidential Candidates,” and Ron Klain, the president’s former White House chief of staff.

It’s Super Tuesday. That means that people in 15 states (Alabama, Alaska, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Utah, Vermont and Virginia) and one territory (American Samoa) are going to the polls.

Usually, Super Tuesday is one of the biggest dates on the primary calendar — a day when a lot of people across the country make their voices heard.

This year is different. There’s no reason to believe that today’s results will alter the seemingly inevitable rematch between President Biden and former President Donald J. Trump. But there are noteworthy primaries in contests that could matter for control of the House and Senate and in important governor races.

Today: Amy Walter, the publisher and editor in chief of The Cook Political Report, previews the Super Tuesday races worth watching.

For a lot of his most loyal supporters, Donald Trump isn’t just the former president or even the potential next president. He is, in their view, the true president — because many of them believe the 2020 election was stolen.

So with Mr. Trump marching toward the Republican nomination and a likely rematch with President Biden in November, we went to this year’s Conservative Political Action Conference for a temperature check on election denial.

Can the MAGA movement move on? Or is the only result they’ll trust a result where Mr. Trump wins?

For the past few months, we’ve been asking our listeners to write in with questions, and we’ve gotten some great ones. Things like: How does polling work? Does Joe Biden’s stance on Gaza present a campaign challenge? And who might Donald Trump select as his running mate?

But as we were sorting through them, an underlying theme started to emerge: People can’t seem to fathom that we’re careening toward a Biden-Trump rematch — and they want to know if anything could alter this seemingly inevitable reality.

So today, with some of our most trusted colleagues on the Times Politics team, we talk through all of the hypotheticals: What happens in the case of a health emergency? How about a criminal conviction? Could this be the year that a third-party candidate breaks through? Or is it too late?

If you had just a few minutes to win someone’s affection, how political would you get? Would you dive right in, or avoid politics altogether? The Run-Up went speed dating in suburban Philadelphia to find out. 

Usually when we’re out in the field, we’re at rallies or campaign events – places where people are vocal about their political beliefs. But for many participants at the dating event, talking politics was a complete turn off. 

This got us thinking: How do political divisions — the things that seem so present on the campaign trail and in polling — actually play out in people’s personal lives? We turned to two of our colleagues -- Anna Martin, host of the Modern Love Podcast, and Jessica Grose, a writer for the Times Opinion section -- for perspective and additional reporting from the intersection of love and politics.

Our listeners have lots of questions about polling.

Questions such as: Is it still relevant? How does it work? How do you get a reliable sample when people don’t answer the phone?

At this point in a usual primary season, still weeks away from Super Tuesday, most of the attention of polling would be on who might capture the nomination.

But this year, with the race all but set, we’re anticipating nine months of polling on two men we already know very well.

Today, to prepare for that future and to answer the many questions on the subject, we go behind the scenes with the New York Times polling team. And Nate Cohn, our chief political analyst, introduces us to “double haters” and other swingy voters he thinks will decide 2024.

Nevada is doing things differently this year. Or at least, it tried to.

The first presidential nominating contest in the west takes place on Tuesday — and on Thursday.

But that’s not what state officials were hoping would happen when they decided to move from a caucus to a primary in 2021.

Democrats got on board — and President Biden is expected to win that contest handily on Tuesday. On the Republican side, however, things did not go according to plan.

A caucus was seen as being beneficial to former President Donald J. Trump, so state party officials — who were aggressively lobbied by the Trump campaign — decided to hold a caucus anyway. The caucus, not the primary, is what will determine which Republican candidate wins Nevada’s delegates.

Nikki Haley, the last remaining significant challenger to Mr. Trump, opted to run in the primary, not the caucus.

So Mr. Trump is effectively in a caucus without a real opponent. And his win is a foregone conclusion.

Confused? You’re not alone.

Today, with our colleague Jennifer Medina, we travel to East Las Vegas to talk to voters about what makes their state so critical — and so confounding — to Republicans and Democrats alike.

President Biden has started to switch gears into campaign mode.

On the trail, he’s particularly focused on South Carolina, which holds the first official Democratic primary contest on Saturday. And one of his first campaign events of the year took him to Emanuel A.M.E. Church in Charleston, for a speech that addressed the dangers of white supremacy.

But a few minutes into the speech, he was interrupted by protesters calling for a cease-fire in Gaza.

Since that day in early January, it seems as if wherever Biden goes, protesters are ready to voice their dissatisfaction with the way the administration is handling the war between Israel and Hamas.

Today: The activists drowning out the president at campaign events. And the Arab American swing state mayor, Abdullah Hammoud of Dearborn, Mich., on why he declined a recent invitation from Biden’s team.

Donald Trump’s victory over Nikki Haley in the New Hampshire primary made two things clear: The MAGA wing of the G.O.P. is ready for his coronation, while anti-Trump Republicans believe the race is far from over.

From inside Trump’s victory party on Tuesday night, we hear from supporters of the former president and from the stars of his orbit, who see themselves as being on the verge of “obliterating the establishment.” And from Tim Draper, a billionaire venture capitalist who is backing Haley.
