TAPPER: “How concerned are you about President Biden’s standing right now?
We have a new poll from CNN.
Most voters — 75 percent, I think of voters — think Democrats have a better chance of keeping the White House if Biden is not the nominee.
And we have a new poll suggesting that Vice President Kamala Harris is actually a stronger challenge within the margin of error to Donald Trump than President Biden is.
Are you concerned about President Biden’s acuity and his ability to win?”
