Hillary had much higher unfavorability numbers and still won. Harris can win and at this point is has the best polling numbers of all the GOP candidates. If there is a better candidate, let them beat her in the primaries and prove it.

No she doesn't. She loses to Castor by 5 points. McCollum loses by 1, Martinez by 2. She has the worst favorability ratings (aside from Byrd), and leads the primary ballot mostly based on name rec.
