Patrick Tompkins, you raise valid concerns about the viability of Joe Biden and particularly his feeling of entitlement that is itself a real stretch -- his career was done before Obama lifted him up. As far as actually winning the election you are perhaps being overly generous and optimistic.
I suggest that Joe Biden graciously remove himself from the race and allow Democrats to have half a chance of winning.
I invite you to rread my article "Let's Get Real -- Joe Biden is not up to the Job" which I publish here on MEDIUM and was in OPED pages of the Houston Chronicle 5/5. Would welcome your thoughts.
