Trump’s base is solid. A third-party run by Haley would be devastating to Biden. A lot of RINOs and softy soccer moms who would otherwise vote for Biden would vote for Haley instead. I say bring it on.
If Nikki tries this she will learn what lawfare is—up close and personal.
There are “sore loser” laws in most states—and lots of lawyers that would have to litigate whether they applied in this case.
Trumps base is solid but he needs a significant number of independents and most of Republicans to win. She would definitely pull some RINO and moderate Republicans and Independents. She could easily make the difference aiding Biden in Purple states.
