Honestly, I don't care if she's the "best candidate for Black people". That doesn't even make sense. You can't vote based on who's the best for Black people because the majority of voters aren't Black.
Republicans genuinely like Donald Trump. They think he did a good job and will vote for him again.
As much as I like Kamala Harris, I don't think she can beat Trump. She doesn't have the following that Trump has. I can't picture an insurrection if Kamala Harris loses.
The Democrats better come up with somebody that can win.
