What am I supposed to be mad for? I've always said the DNC favored Clinton because she was a democrat. That was always clear.
But Bernie's shortcomings are largely because he started late and failed to resonate with older black voters in the south as well as Clinton did.
If you think Russian collusion and influence was a nothing burger, then I'm not sure what this does for your position.
The DNC has flaws, but using those to overlook failures in his primary campaign is the same as Clinton supporters overlooking her own failures.
With regards to Bernie, I just don't see a path for a 79 year old man to win a nomination in today's climate. I've said that repeatedly. Unlike you, if he were the nominee I would have voted for him and not spent my entire political existence complaining that Hillary lost. I mean hell, I don't do that now.
