Haley is a woman, so she might attract more educated young college white women to the conservative side, which group tends to vote democrat.

This only works under the assumption that literally every Trump voter will just vote for the R if he doesn't get the nomination, so they can add more on top of it via diversity. And that there are zero people who might dislike her enough to sway their vote.

That "we already own this market, so we can focus on grabbing another" mindset is not only retarded and prone to failure, its absolutely insulting because it assumes they own their voters.
