Can't think of any Dem. 33 or older with name recognition that can't be outed with corruption or worse 5 minutes after his/her hat is in the ring. Only viable candidates are those not affiliated with the corrupt party leaders. And none of those will be nominated.
Plus, they set the standard with the Jim J crap. Nasty, unprovable allegations from anyone they have known in the past 30 years can be repeated and smeared all over. They should stop assuming we are the nice guys and will not use their destruction tactics against them when the time is right.
