One of the biggest problems of the current administration is that it doesn’t have an effective salesman. I suspect some of this is by design–Biden has deliberately avoided doing anything that makes him look like Trump–but part of it is due to Biden’s weakness as a public speaker. How can the Democrats deal with this problem?
The logical option is Harris. If she isn’t up to it, someone else will have to step in, or the GOP will fill the vacuum. My best guess would be Warren; after all, as we know from the 2020 campaign, there’s nothing she enjoys more than a good fight with the right.
