Where’s the question will you vote for Biden if he remains the nominee? Where’s the question will you change your vote for the other old man if Biden remains the nominee?

"Vice President Harris fares as well as Biden against Trump." The closest answer we seem to get is Harris does about the same (slightly better, but within the margin of error). So this seems to be more of a "none of the above" voting block. Not great when Trump's base is so eager.
