And now ABC also projects that Haley will win Vermont. The race remains super close, however, and it’s not yet clear how delegates will be awarded.

Polls have now closed in California, where all parties run on a single primary ballot (other than in presidential races). Unfortunately, neither party is particularly popular in the state. According to a February survey from the Public Policy Institute of California, likely primary voters in California don’t have a favorable view of either political party: The Democratic party is underwater by 10 percentage points, with 44 percent of likely voters saying they have a favorable impression of the party and 54 percent saying they have an unfavorable view. The Republican party fares even worse, with a net favorability of -55 points, 22 percent favorable and 77 percent unfavorable.

The New York Times and the Associated Press have projected that Haley will win the Republican primary in Vermont, making it the second win for her after Washington, D.C. (ABC News has not yet made a projection in this race.)

While Trump remains ahead on the delegate count, the win could give some juice to her campaign. She's vowed to stay in because she says that Trump and Biden are both too old and out of touch, and she has been capturing a sizable minority of primary voters who are unhappy with the former president in many states across the country. Still, she'll need to get a majority of the final vote to take all of the delegates, and that remains up in the air. With 92 percent of the expected vote in, she has 49.7 percent to Trump's 46 percent. If neither candidate reaches 50.1 percent, they'll split the state's delegates.

North Carolina’s 13th District is yet another Democratic-held seat that North Carolina Republicans redrew this year to be safely red. Unsurprisingly, the GOP primary attracted a wide field, and with 67 percent of the expected vote counted according to the Associated Press, attorney Kelly Daughtry is in first place with 29 percent, followed by former federal prosecutor Brad Knott with 18 percent, businessman DeVan Barbour with 17 percent and yet another businessman Fred Von Canon with 16 percent. As a reminder, if no one gets 30 percent, the runner-up is entitled to request a runoff.

Back in late January, we wondered if the 2024 Republican presidential primary might be the shortest in modern history. But because Haley continued to contest the race until Super Tuesday, the competitive period of this year's GOP contest ended up falling short of setting any records. Still, it was undoubtedly on the quick side, historically.

The 2024 Republican race lasted 52 days from Iowa through today, during which time all states and the District of Columbia held 25 contests. The March 6 effective end date puts it just behind the record earliest end of a nomination season (March 3 in the 2004 Democratic contest) and the number of state-level elections (19 in the 2000 Democratic race). Nonetheless, going back to the 1976 election cycle, this year's Republican campaign was much shorter than the median number of competitive days (85 days), state-level contests (39) and end date (April 9).

To be clear, measuring the effective end date of a nomination race's competitive period is not always cut and dry, although it was this time around. We based our approach on political scientist Caitlin Jewitt's work on presidential primary competition, which classified a candidate as their party's presumptive nominee either when all viable opponents have dropped out or when they clinch a delegate majority from the results of primaries and caucuses. In Trump's case, Haley was his last viable opponent.
