Manny, a CNN poll has the figure that 75% of Democrats wanted a nominee other than Biden. Most were happy with his achievements but thought he was too old for a second term.
The Biden camp is holding out to get beyond the time to replace Biden. They are almost there but still can't quite close the door. Why? Because he could too easily finish up like Hillary Clinton, savvy analysts are all too aware of this.
Biden is a proven lousy campaigner, and there are limits on his staff's ability to prop him up. Look what happened in Hanoi at his press conference.
Please read my "Just Watch Me." We Have Joe, and It's Time to Go.
Best to you.
