Smith is an outspoken, MAGA-style firebrand who hasn’t managed to pull out a win in the area and would have been a more appealing (read: weaker) opponent for the freshman congressman in this swingy district. As I mentioned earlier, the 1st District has long been a Democratic stronghold — it hasn’t elected a Republican in over 140 years — but after redistricting, it was redrawn to become a tossup district, and is set to be the only real competitive Congressional race in North Carolina this fall.

In North Carolina's 1st congressional district, Buckhout is projected to win the Republican primary, according to The New York Times. We wrote about this earlier, but her win comes on the strength of national Republican Party efforts to make her the nominee over two-time candidate in the district, Sandy Smith, a candidate with a more Trumpy profile. Buckhout will take on Democratic Rep. Don Davis in November.

With more than 90 percent of North Carolina's expected vote in, we can now say more about the patterns in that state. First, Trump is romping statewide, with 75 percent to Haley's 23 percent. But where is Trump doing especially well? In counties with few people with college degrees, sure. But also in counties with lower population density and more Black voters. That said, it doesn't mean Trump is doing well with Black GOP voters — preliminary data from the North Carolina exit poll suggest that in fact non-White Republican primary voters were a bit less supportive of Trump than white Republican primary voters. Instead, Trump is doing especially well in the counties with more Black residents (regardless of whether they're voting tonight or not).

With 81-year-old Rep. Kay Granger set to retire, the primary race to replace her in Texas's 12th District looks like it may go to the more establishment GOP candidate: state Rep. Craig Goldman, who is currently leading with 46 percent and 78 percent of expected votes in. He'll need to get 50 percent of the vote (plus one vote) to avoid a runoff with local businessman John O'Shea, a more Trumpian candidate who currently has 25 percent of the vote.

If the polls are right, there will be very little drama tonight in presidential races: Trump has massive leads over Haley in virtually every state. For instance, here's what our primary polling averages say in the six states with enough polling to calculate one:

Trump also leads by at least 42 percentage points in the few state-level polls we have this year from Alabama, Maine, Minnesota and Oklahoma. His lead is smaller, though still substantial, in the most recent surveys of Utah (27 points) and Vermont (30 points). Unfortunately, we're flying blind in the last three states; we don't have any polls of Arkansas since last fall, or any polls of Alaska or Colorado, period.

But what if … the polls are wrong? Even in the states where we've calculated averages, there is precious little truly recent polling. The only polls of Super Tuesday states conducted entirely within the last month were four of California, two of Maine, one of Minnesota, two of North Carolina, one of Texas, one of Vermont and one of Virginia. That's not a lot of data to go off.

Plus, primary polls so far this year have overestimated Trump's margin over Haley. This isn't necessarily unusual; since 2000, presidential primary polls have had an average error of 9 points. But the fact that the direction of that error has been consistent so far is … interesting. We usually caution against trying to predict the direction of polling error in advance, but this could — could — indicate that pollsters' likely-voter models for the primary are too weighted toward the Trump wing of the GOP.

As Geoffrey and I wrote yesterday, there are certain states — Colorado, Massachusetts, Vermont and Virginia — that seem demographically favorable for Haley. Despite what the polls say, I wouldn't be totally shocked if Haley pulled off a win in one of them. As noted, Colorado hasn't seen any polling this cycle, and Massachusetts hasn't seen any in a month. And while a poll gave Trump a 30-point lead in Vermont a few weeks back, the most recent poll of Virginia put Trump's lead over Haley at just 8 points among likely voters.
