Earlier I wrote that although more Republican women are running, the GOP conference is still largely represented by men. North Carolina, where polls just closed, nicely illustrates some of the reasons that Republican women continue to trail Democratic women by such large margins, in Congress. North Carolina has low female representation in their state legislature (which is just 29 percent female), and that limits their recruitment from that pool. And in today's open primaries in safely Republican districts where the GOP primary will effectively decide the next representative, women aren't among the most competitive. As Kaleigh wrote earlier, in the 8th District outside Charlotte, the two GOP front runners are state Rep. John Bradford, and Baptist minister Mark Harris. And in the 10th District, the race is largely between state Rep. Grey Mills and Pat Harrigan, a gun manufacturer. There are several non-incumbent women running in the state today, but none of the groups we are watching that support Republican women (Winning for Women, VIEW-PAC, E-PAC or Maggie's List) have made endorsements.

ABC News projects that Trump will win Virginia's Republican presidential primary. We'll have to wait to see how the final totals break down, but this isn't much of a surprise considering Trump had comfortably led most polling of the GOP race in the Old Dominion. Now, Virginia's more highly-educated population and Trump's weaker performance there in 2016 probably makes it one of Haley's better states tonight. Yet the fact the result there has already been projected less than a half hour after polls closed may foreshadow a Trump sweep tonight. Loudoun County's early returns demonstrate how Haley is coming up short: Sitting outside of Washington, D.C., in vote-rich northern Virginia, Loudoun is a Democratic-leaning and highly affluent county — the kind of place Haley has done better in. But she's still trailing Trump there by around 6 percentage points, 52 percent to 46 percent, with one-third of the expected vote reporting.

While we wait for polls to close and results to come in, I'll muse about the bigger picture here. Depending on how things go, this might be the end of Haley's candidacy. But either way, we should think about what's at stake in the contest between her and Trump. Broadly speaking, she has increasingly presented herself as the Trump/MAGA alternative. In some ways, she's made this distinction clear, most recently by suggesting she might not stick with her pledge to support the party nominee, and denouncing his actions on Jan. 6, 2021.

But the rest of her candidacy has been mostly about other stuff — how she'd be more competitive against Biden, and about giving voters a choice in the primary. On one of the main issues that set Trump apart from the rest of the GOP field in 2016, immigration, Haley has also been very conservative, signing one of the toughest state bills when she was governor of South Carolina and adopting Trump's language about toughness at the border. As in 2016, Trump seems poised to soundly defeat his primary rivals. But in terms of the real GOP alternatives to Trumpism, it's definitely not 2016 anymore.

The main concerns about the top candidates didn’t resonate with primary voters in North Carolina. Seventy-five percent of likely North Carolina Republican primary voters said that Trump’s criminal indictments were not a serious consideration for them, according to a February poll by Emerson College/The Hill, while 25 percent said the indictments raised “serious doubts” in their minds about voting for Trump. Democratic primary voters in the state were more worried about Biden’s age than Republican primary voters were about Trump’s indictments: 34 percent of likely Democratic primary voters said Biden’s age raised serious doubts about voting for him, while 66 percent said it was not a consideration.

The biggest downballot race in California is its U.S. Senate contest. Although 27 candidates filed for the race to fill the seat of the late Democratic Sen. Dianne Feinstein — who died last fall — the four leading contenders are Democratic Reps. Adam Schiff, Katie Porter and Barbara Lee, plus Republican Steve Garvey, a former Major League Baseball player. The front-runner appears to be Schiff, who is polling at around 25 percent in 538's California primary polling average. This puts him just a bit ahead of Garvey and Porter, who are right around 20 percent for the coveted second spot. Behind them is Lee, who is polling just under 10 percent.

The race has largely centered on Schiff and Porter, both of whom are fundraising powerhouses. As of Feb. 14, Schiff had brought in $29.8 million in net contributions, while Porter had collected $16.7 million, putting them each well ahead of Lee ($4.8 million) and Garvey ($2.1 million). The two leading Democrats also brought over huge sums left over from their House accounts — $21 million for Schiff and $7.4 million for Porter.

In the final weeks, Schiff has tried to use his massive campaign war chest to push Garvey into second place. Schiff has run ads that attack Garvey for his conservative views and past support for Trump, but the spots intend to raise Garvey's profile among Republican voters. By doing that, Schiff could help Garvey consolidate the GOP vote and finish ahead of Porter, relieving Schiff of a demanding general election campaign against the fellow Democrat. A pro-cryptocurrency super PAC may also help Schiff out, after swooping in with $10 million in outside spending seeking to derail Porter.
