re: Biden is not a leader and will be walked all over by radicals in Congress

Yes

I think the greatest danger are the radicals who will fill out lower level positions in the administration.

I assume Biden and Kamala don't really care about policy, provided they're in charge, and continue to get rich. And so they'll just let these radicals do what they want.

And because they don't care, they won't take the time to think through the repercussions of what their administration does.
