With 70 percent of the expected vote reporting in Vermont, Trump and Haley are tied again at 48 percent each. If Haley wins there, it might compel her to stay in past tonight, but the overall delegate math is still against her.

Want to know more about territories like American Samoa, which participate in the nomination process but aren't states — and thus don't have Electoral College votes or representation in Congress? I recommend this fascinating book, "The Not-Quite-States of America" by journalist Doug Mack. It explores the contradictions in the status of these areas and how it affects the people who live there.

Well, well, well. It turns out neither Trump nor Biden will sweep every presidential nominating contest this year. ABC News can confirm that Biden has lost the Democratic caucuses in the territory of American Samoa to Jason Palmer.

Who is Jason Palmer, you ask? One of the many no-name candidates who runs for president every year. According to DDHQ’s Derek Willis, Palmer actually visited American Samoa to campaign, which explains how he was able to accomplish something that neither Marianne Williamson nor Dean Phillips has been able to do this year.

P.S. What’s up with American Samoa and Democratic caucuses? You may recall that, back in 2020, it was the only state or territory to vote for Michael Bloomberg.

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.
