When you get right down to it there's a fundamental question of what voters we'd lose nominating someone so clearly authoritarian sympathetic and likely anti-Islamic, a Tucker Carlson guest-ing right winger with no track record of supporting real progressive causes. The group who votes Democratic isn't a given under the most ideal of circumstances much less the current situation of state governments hostile to voters turning in ballots for Democratic candidates. We can stipulate that she appeals to a certain segment of voters but your argument just begs the question of whether chasing these voters in this way is even worth it.
