Don't forget to mention that 50% of the people from the same poll also think Trump should drop out.
I would be interested in seeing a more detailed break-down of this poll. From the numbers given, 33% are non-Democrats. This could mean that up to half of that "67% of Americans" saying Biden should drop out are actually people whose opinion in this poll doesn't really matter. What I really want to see is how many Democrats think Biden should drop out, versus how many Republicans think Trump should drop out. (It would also be interesting to see the breakdown for both candidates from independents.)
