Yeah, 'coin flips' and this. The Democratic Party is a real mess. What's going on?
Not a thing, this is and has been the DNC process for 30 something years... Bernie knows the process, he can get commitments from unpledged delegates if he wants them... he just hasn't even tried to get them, from what I can tell?
Personally, I don't believe Bernie wanted to be President when he chose to run...back then his chances were nil in winning, he chose to run anyway, to get his political message out there....
