Nikki Haley is by far the most impressive member of the Trump administration. If she were to run there is no Republican or Democrat who could come close.... as it stands right now.
(Trump is creating a greater legacy in 6 months than anyone in my lifetime. He may decide he has nothing left to prove and not run for re-election.)
A wild fantasy scenario that won't happen.
