CNN reporter declares Biden’s polling as incumbent in presidential primary is historically ‘weak, weak, weak’

What about Joe Biden? How is he doing in terms of an incumbent in a primary? Yeah, You know, everyone's saying that Donald Trump's doing weak, weak, weak. It's actually Joe Biden, in my mind, in the primaries that's doing weak, weak, weak, at least relative to history, because right now he's getting 87% of that primary vote for an incumbent. But that's actually the lowest. That is actually the lowest for any candidate since George HW Bush back in 19192 when Pat Buchanan challenged him. Of course, we all remember, at least I remember, that George HW Bush lost re-election in the fall to Bill Clinton.
