The average voter outside of her state would barely know who she is other than she was a governor somewhere. I doubt most would even know she was in the primary against Trump. And her cable news presence has been minimal. It's not dislike, but indifference in her case.I disagree on Haley, perhaps you are correct about Cheney as many Dems dislike him as well as many Repugs but Haley has her following of more moderate repugs who dislike Trump.
And those moderate Trump haters are already voting for Harris. They are baked in. Being voters are not going to base their choice on her recommendation.
