I'm not following what point you're trying to make here.
Kamala Harris' team is going to make known any and all Republicans who support her in an effort to try and convince Independents and Republicans who don't like Trump to get out on Election Day and vote for her, particularly in swing states. That's just smart politicking to try and beat Trump.
I would guess the average Democratic voter hates Dick Cheney but understands that when people as awful as Liz or Dick Cheney actually endorse Harris publicly, it is a clear indication just how dangerousTrump and MAGA really are.
Ona daily basis, Trump and Vance make no attempt to hide their hatred of women, drag queens, gays, lwsnians, immigrants, people of color, etc. While Harris and the Dems defend those groups publicly, legally and politically.
Whether the Left is perfect or not is not the point. MAGA would like to see Chappel Roan censored, disempowered, and possibly imprisoned.
I'm not calling Chapell a centrist, I'm saying she being foolish and failing to exercise her influence. She couldn't instead say "I don't disagree with Harris on A, B, C, but I support her candidacy because of basic human rights, and here's what I would like her to commit to".
Instead, she's failing to help her fans understand what's at stake here, and they may sit on the sidelines come election day
While I generally agree with what you said, I'm not convinced Trumpism doesn't die or at least go back into its hole when he goes away.
Trumpism is really nothing more than a power grab by an authoritarian who uses white nationalism rhetoric to enthrall the baser segment of society and amass a voting base to maintain power long enough to undermine democracy.
Trump could die tomorrow, and there's a dozen wannabe authoritarians that would try to fill that void and run on Trumpism.
I'm not convinced there's any MAGAts out there than can inspire the base, get the MAGAts in Congress to coalesce behind them, and solidify the financial support of the Musks, Thiels, etc of the oligarchy.
