Is Burr not going to run for re-election?
If so- Burr will be much much tougher to beat than Tillis. If Jackson has goals for being in the Senate- his shot is most likely 2020, or otherwise 2026. (I don't think anyone will be able to beat Burr at this point. Haven't seen polls, but it feels like Burr is a lot more popular & stronger candidate now than he was in prior elections.... Seems liked he's sort of reached that threshold that will make him really tough to beat.
He
promised in 2016 that if he won (which he did), this term will be his last.
And if Trump wins re-election in 2020, Senator Burr would be well-advised to keep his promise. I don't fancy his chances in a Trump midterm year. Not in a swing state like North Carolina, at any rate.
