Yes, I agree with that. The thing is that the Israel/Palestine issue is unlikely to subtract voters in the states that Biden really needs, with the exception of Michigan. That seems to be largely a university/liberal issue, which is why the Russians are still backing Jill Stein. I know my own kids and, seemingly, most of their friends will hold their noses and vote for Biden in the end.
And RFK is tricky. He's certainly a worrying development, but I suspect as the campaign ramps up and he becomes more visible (and his family continues to be outspoken) his sheen will dim.
But I could certainly be wrong.
Edited to add - a lot of the stuff I listen to and read seems to back the theory that Trump's base is now set, and Biden's is still more elastic, which ultimately could make him or finish him.
I like this podcast a lot
