The 2026 U.S. Senate election in North Carolina promises to be one of the most hostly contested U.S. Senate election--and possibly the most hotly contested election period--in 2026. The incumbent Republican Thom Tillis has come under fire from his own party and, not surprisingly, from the Democrats as well.
While I don't believe that Tillis is likely to lose the primary, the outcome of the General Election is much more unknown. The party of the President always loses seats in the midterm year and Tillis is the only Republican incumbent Senator up for re-election in a purple state.
The only problem for the Democrats: they don't have a candidate yet.
Former member of Congress and member of the North Carolina General Assembly Wiley Nickel announced he would run for the seat in December, 2023 and has filed for the seat with the FEC, but more recently he has seemed more uncertain about his candidacy. A few weeks ago, he said in an appearance on the Muck You podcast that he was "looking at a Senate run." It appears that he's not a candidate. At least not yet.
The reason for the uncertainty, it would seem, is that he's waiting for former North Carolina Governor Roy Cooper to make his a decision. Cooper is currently teaching at Harvard while he "mulls" a U.S. Senate run.
So, how long does Cooper have? There's no definitive answer to that question, but for some guidance, I catalogued the announcement date for prominent non-incumbent US Senate candidates from the 2004, 2008, 2010, 2014, 2016, 2020 and 2022 elections. I also included Andy Nilsson, Tillis' first challenger in the Republican primary in 2026. The NC primary election dates move around more often than a circus clown, so to provide some measure of comparability, I calculated the number of days between the announcement and the primary date for that cycle. Today (April 1, 2025) is 326 days until the 2026 primary; that is also indicated on the graph.
As you can see from the graph below, if Cooper announced today, he would be later than winning candidates Thom Tilllis (2014), Ted Budd (2022) and Richard Burr (2004), as well as virtually every prominent candidate in 2022--Cheri Beasley, Pat McCrory, Jeff Jackson and Mark Walker.
At the same time, if he got in today, he would get in before Erskine Bowles (who won the Democratic Primary in 2004), Cal Cunningham (who won the Democratic primary in 2020), Marjorie Eastman (2022), Jim Neal (2008), Elaine Marshall (who won the 2010 Democratic primary), Deborah Ross (who won the 2006 Democratic primary) Cal Cunningham (2010), and Kay Hagan, (who won the 2008 Senate election).
