Sanders is already running; Biden brings nothing new to the table except to be the establishment spoiler and the last to announce because he has too many 'roadblocks' to consider..his voting record speaks for itself..the pictures with children- the most damning whether nor not anyone cares to admit..as a mother, i'd be vomiting in my mouth to vote for that freak.
the voters booth is private for a reason.
Polls, Henny Penny's?
Biden's numbers will never be higher than when he announces- this goes for all candidates and is a proven fact.
