March 5 was Super Tuesday — the biggest election day of the year until the one in November! With former President Donald Trump projected to win 14 of the day's 15 GOP presidential nominating contests, former U.N. Ambassador Nikki Haley announced Wednesday morning that she is suspending her campaign.

It was also the first downballot primary day of 2024, with important contests for Senate, House and governor in states like Alabama, California, North Carolina and Texas.

Voters are choosing candidates for 7 of the 15 seats on the powerful Los Angeles City Council

In Los Angeles, voters will decide which candidates will face off in November for seven of its 15 city council seats. Arguably one of the most powerful city councils in the country, it's been riddled with scandal the past few years.

In 2022, leaked audio revealed then-City Council President Nury Martinez making racist comments in a meeting that included two other council members, which ultimately led to her resignation. One of the other members who was part of that conversation, Kevin de León, remains on the council after surviving months of protests, calls for his resignation (including from President Biden) and a recall attempt. Today he's running for a second four-year term against seven challengers, including two former political allies, state Assemblymembers Miguel Santiago and Wendy Carrillo. Santiago specifically has scooped up the endorsement of the key labor unions that once backed de León, as well as the Los Angeles County Democratic Party.

Overall, policing, affordable housing and homelessness are big issues in the city, the second largest in the nation, and how the council decides to handle those issues in the future could help set the tone for the rest of the country. Today's elections could help decide, in part, how progressive the council will be: In other races, business interests have been targeting progressive Councilmember Nithya Raman, and spending to bolster the council's only non-Democrat, independent John Lee, who faces an ethics probe and a more progressive challenger.

6 downballot races to watch in Texas

The race for Senate in Texas will surely be one of the most closely watched races of the year. There are nine candidates running in the Democratic primary to unseat Sen. Ted Cruz, but the front-runner is Rep. Colin Allred, a former NFL player and civil rights attorney who has represented the Dallas area since 2019. Allred has raised the most funds (to the tune of $21 million) and attracted donations from party influencers. The biggest question tonight is whether Allred can pull more than 50 percent of the vote and avoid a May runoff.

There are also a handful of U.S. representatives in Texas with at least some danger of losing their seats tonight, as Jacob covered earlier. Keep your eyes on Houston Democrat Lizzie Fletcher in the 7th District, who is facing a challenger from the left in Pervez Agwan; Democrat Sheila Jackson Lee in the 18th District, whose run for Houston mayor last year destabilized her campaign against former Houston City Councilwoman Amanda Edwards; and Republican Tony Gonzales in the 23rd District, who is facing multiple challengers and may also end up in runoff territory.

And there are some open seats up for grabs, creating hotly contested primary races. In the 12th District around Fort Worth, it's the familiar GOP battle between results-focused conservatism of the old guard versus the firebrand populism of MAGA. State Rep. Craig Goldman represents the establishment candidate, while business owner John O'Shea fills the role of MAGA candidate. In the 26th District, two far-right candidates are leading a slate of 11 to fill the open seat in this deep-red stronghold: Brandon Gill, who heavily promoted his father-in-law, Dinesh D'Souza's, conspiracy-theory-laden film "2000 Mules" on his website, and Southlake Mayor John Huffman. And lastly, with Allred making a play for the Senate, his Dallas-area 32nd District is up for grabs. Ten Democrats are running in the primary, though two in particular seem to be leading the pack: state Rep. Julie Johnson and trauma surgeon Brian Williams.

Haley’s favorability ratings in Super Tuesday states aren’t encouraging for her

While we don’t have data for every Super Tuesday state, in the ones we do, Haley’s favorability lags far behind Trump’s among Republican voters. In Texas, an early February poll from YouGov/The University of Texas shows GOP voters there have a particularly dim view of Haley; the survey shows Haley 4 percentage points underwater among Republicans, with a 36 percent favorability rating and a 40 percent unfavorability rating, while Trump is has a massive positive net approval rating of 71 percent (83 percent favorable and just 12 percent unfavorable).

While not quite as dismal as in Texas, Haley’s numbers in other Super Tuesday states lag far behind Trump’s. For example, a Morning Consult/Bloomberg poll from mid-February in North Carolina has Haley at net +18 percent favorability (52 percent favorable, 34 percent unfavorable) among registered Republicans, compared to net +64 percent favorability for Trump (81 percent favorable, 17 percent unfavorable). An early February poll in Maine from Pan Atlantic Research shows Haley at net favorability +15 percent favorable (50 to 35 percent), compared to Trump’s net +52 percent favorability rating (76 to 24 percent).

In Vermont, polls suggest Haley might perform a little better than in other states, but her favorability is underwater, according to an early January survey from the University of New Hampshire Survey Center. That survey had Trump with a lower favorable rating than he enjoys in other states, net +20 points (57 to 37 percent), but Haley had a net favorability of -9 points among likely primary voters: 32 percent favorable and 41 percent unfavorable.

The Supreme Court didn't upend the race

On Monday, the U.S. Supreme Court overturned the Colorado Supreme Court's decision that ruled Trump ineligible for the state’s primary ballot on 14th Amendment grounds (i.e., that he had participated in insurrection). The court unanimously found that states don't have the power to disqualify federal candidates under the 14th Amendment. The upshot of the decision is that Trump is eligible to run for president in every state.

Despite the splashy headlines about yesterday’s decision, it really doesn't change anything about today’s presidential contest. Trump's name was already included on the ballots that Colorado voters are submitting today, after the Colorado court had stayed its own decision pending the federal appeal. And while some Democrats had hoped that the Supreme Court would rule Trump ineligible everywhere — thus abruptly ending his presidential campaign — that was never going to happen. The Supreme Court is dominated by conservatives, and even the liberal justices seemed unpersuaded by oral arguments.
