He would have a shot for the nomination if Trump loses next year. Otherwise, Pence seems to be in a good position for one-on-one with Nikki Haley. But I doubt he will ever be president.
What is it with the Nikki Haley hype? She’d never win the nomination.
Nikki Haley actually has a lot of strenghts: Experience in statewide elected office and on the international stage. She seems acceptable for Trumpers and non-Trumpers alike. And she may win a little more than usual minority/women voters. At least enough to make a general election very competitive. If I was a Democratic president elected in 2020, I wouldn't want to run against her instead of Ted Cruz or Mike Pence.
