Trump was a nobody in GOP until he became somebody in the GOP by crapping all over GOP established politicians. I am not saying that Dean Phillps has the name recognition of Trump, but Obama wasn't that known either until 2008 primaries. America/World loves to cheer for an underdog so I think Dean Phillpis can elevate democratic party from an untrusted and unauthentic organization it has become.
Wow, I did not realize Bernie is and has been independent since 1978 and has only been democrat during primaries. Thank you for pointing that out. Well, that explains why DNC establishment made sure he does not come up to the top. Bernie's popularity during 2016 and 2020 primaries are to me a clear evidence that DNC needs fresh people and fresh ideas.
Personally I don't believe the establishment dems (clintons, obamas, pelosi etc...) will ever relinquish any power to someone like Bernie, who wants to fix the system. They don't want to fix it, they want to keep it exactly as it is.
