Like who?
Although new in the Senate...Tenn’s Senator (Marsha Blackburn) is one prime candidate. She has a business background and generally liked by most everyone in Tenn.
Lindsey Graham would have been a joke two years ago, but ever since McCain passed on, and Graham has been on some massive turbo blast in defense of Trump last fall...he might be someone to have around in a rough 2020 campaign period.
Ted Cruz could be brought up, but I think he bound to the Supreme Court between 2020 and 2024 (maybe RBG’s eventual replacement).
Finally, I came to view John James from Michigan in last fall’s Senate election (note: he didn’t win...missed by 7 points). He’s an Army Academy grad....business background...fairly smart, and 37 years old. In the black community, he’d openly challenge Democratic values. Did eight years in the Army. All-round five-star VP guy.
