Biden is the new Clinton. A significant number of Progressive/Liberal Democrats will not vote for him. The Dems will shove him to the front of the pack (cheating/fixing the Primary) and enough Democrats will either not vote or vote third party rather than vote for Joe Biden,
They will force him as the candidate and they'll lose again on 2020 because they have split the Democrat Party (The Democrat Establishment) into factions....all the candidates will destroy each other over the coming year/months.
Former Vice President Joe Biden, in an online video Thursday, officially declared his candidacy for president in 2020, capping off weeks of intrigue and media speculation.
The media loves him, rewarding him with unlimited positive coverage. They can make or break these candidates. So far, they have not been able to break the one they hate most, thank God.
