Of course the DNC is in the tank for Hillary!! You have to be a blind and deaf mute to think otherwise!
Hillary is running in place for Biden, who, as VP, is the normal standard bearer for the continuation of Democratic control of the Whitehouse.
However, there is nothing wrong if the Secretary of State takes his place. Hence, Hillary is the replacement standard bearer of the Obama administration.
GHWBush after Reagan
It is like Al Gore running after Clinton two terms
Like Dick Cheney--oh wait, he nor anyone else wanted to continue the GWBush administration!!
