With 24 percent of the expected vote reporting, Trump is leading in Texas by 53 percentage points. Despite Trump's 65-point lead in the polls, likely GOP primary voters in Texas thought the race would be close in pre-election polling. In a February survey from the University of Texas at Tyler, just 17 percent of likely GOP primary voters in the state thought Trump would win by a large margin, while 21 percent thought that Trump would win in a close election. Another 6 percent said they thought Trump would win, but weren't sure of what the margin would be. Most of the rest, 46 percent, said they weren't sure who would win, and just 3 percent thought Haley would win.

ABC News projects that Trump will win the Tennessee Republican primary, his fourth win of the evening (and the night is young). Demographically, Tennessee was one of the best states for Trump, and it hasn't let him down tonight: He's currently leading 81 percent to 16 percent.

Trump looks well on his way to a clear victory in Virginia. With 46 percent of the expected vote reporting, he leads Haley 66 percent to 32 percent.

If we look at a map of Virginia's counties and independent cities, we can see how Haley failed to break through. To be competitive, Haley needed to perform well in the state's three major metro areas: Northern Virginia outside of the nation's capital, around the state capital of Richmond and in Hampton Roads, the southeast corner of the state. Yet she's mostly striking out so far.

So far, she only leads in the inner D.C. suburbs (including the state's largest county, Fairfax) and in the city of Richmond proper. She will probably gain as Fairfax reports more, but critically, Trump leads in Loudoun and Prince William counties, the other two big population centers in Northern Virginia. Trump is also ahead around Richmond and leads everywhere in Hampton Roads. And his strength in the rural areas is very strong, much as was the case in the 2016 GOP primary here. Haley holds leads in the city of Roanoke and in the Albemarle County-Charlottesville City area, but it's far from enough to make the race interesting.

ABC News also projects that Biden will win in Vermont and Oklahoma, two of the states I'm watching tonight. Biden is a favorite to win across the country, but there is still a Democratic primary tonight.

Voters are choosing more than their parties' presidential nominees tonight. In five Super Tuesday states, they're also deciding on candidates for statewide and local offices. Several consequential judicial elections are being held tonight, for positions on state supreme courts in Alabama, Arkansas and Texas, and on the Criminal Court of Appeals in Texas.

In Arkansas, nonpartisan general elections are being held to fill two vacancies on the Supreme Court, creating a game of musical chairs among the sitting justices that could potentially accelerate the already-conservative court's rightward shift. Chief Justice Dan Kemp is stepping down, and three of the four candidates running to replace him are already sitting on the court, while another sitting justice is angling to move to a different open seat on the court. The shuffle could leave two vacancies that would allow conservative Gov. Sarah Huckabee Sanders to name replacements to finish their terms.

Alabama's Supreme Court Chief Justice Tom Parker, who recently made waves nationally with a ruling that frozen embryos used for IVF are children, is also retiring because of the state's mandatory retirement age. Two candidates are running for the Republican nomination to replace him: sitting Associate Justice Sarah Stewart (who had to give up her seat to run for the top slot) and former state Senator Bryan Taylor. While Stewart joined the 8-1 majority opinion in the IVF case and both candidates have defended the decision, Taylor has claimed that Stewart is the "most liberal" justice on the all-Republican court, and received a huge influx of outside spending from conservative anti-abortion group Fair Courts America. Whoever wins will likely face (and defeat) Democrat Greg Griffin>) in the general election.

In Texas, Supreme Court Justice John Devine is facing a primary challenger who has questioned his ethics, but a bigger political feud is playing out in other races. Allies of Republican Attorney General Ken Paxton are funding primary challengers to three Criminal Court of Appeals judges who ruled against him in a voter fraud decision, limiting his power to prosecute those cases. And as Nathaniel noted earlier, Paxton, who had been accused of abusing power to protect a political donor, has also endorsed primary challengers against 34 of the 60 Republican legislators who voted to impeach him last year.
