We won't know whether or not President Donald Trump will win a second term for (at least) six more days.

But ambitious Republicans aren't waiting around to see if Trump can pull off a major upset. They're out campaigning for candidates in what is rightly understood as the early jockeying for the 2024 GOP nomination.

Earlier this week, Nebraska's Sen. Ben Sasse was at the University of Iowa to deliver a lecture titled "American Order and Disorder, at Home and Abroad." And on Tuesday, Sasse was back in Iowa to "knock on doors for his friend Joni Ernst," according to James Wegmann, communications director for the senator.

Last week, former United Nations Ambassador (and former South Carolina Gov.) Nikki Haley was in Iowa stumping for Ernst. Arkansas' Sen. Tom Cotton, who is coasting to a second term this year, has made stops in both Iowa and New Hampshire in recent months.
