The entirety of the Democratic Party's leadership under Obama needs to be wiped clean so we can start over. Obama himself wasn't bad or incompetent, but all those who ran the party underneath him which, to a certain extent, was a reflection of his poor leadership skills, watched the party's numbers being decimated at every level of government and did absolutely nothing to halt or reverse it except point fingers and name call.
In reality, DWS was merely a symptom of the party's disease.
The issue is that Obama never wanted to get involved in the party politics side of things and always despised it. He just saw himself as above and beyond that. In hindsight, I think he should have cleaned the ship the second he became President, but his major flaw crept in, which seemed to be that he just has too much faith in other people. I think in another time and place that kind of leadership would be suitable, but what the party needed at the time was someone like LBJ.
And the Democratic party will be paying for this for many years. Obama needed to have a Karl Rove in the White House who had a one track focus on party politics at all times. Instead, Obama tore town the 50 state strategy and filled the DNC with hacks that only cared about getting him re-elected in 2012.
Democrats who blindly followed Obama's tearing down of the 50 state strategy and allowing the state Democratic parties to rot away now.deserve what they get in President Trump.
