No.
The DNC lost all credibility last presidential cycle. They cheated Sanders in order to foist the most unpopular candidate anyone can recall ever being nominated.... and they lost to a moral-less, spastic con man and failed TV show host because of those actions. Thats it. Sanders capitulation in that moment showed me that he cant be truly trusted. I like many of his ideas and policies, but hes not strong enough or willing to fight hard enough to gain success. He rolled right over when it counted most last time.
So the DNC is corrupt and Sanders is weak.... without Gabbard to keep this situation in line, I have seen nothing to inspire my confidence that Sanders will be able to handle the presidency. He (as most presidents do) needs an enforcer. If he thinks the people who haven't shown the ability to do so yet or even worse, the people who already cheated him and are actively working against him now, are the pool to draw that talent from.... he will lose to Trump irregardless of his getting (or getting cheated out of) the Democratic party nomination.
The whole "Trump bad so vote blue no matter who" mantra is not a successful election strategy and if the DNC is counting on it again in 2020, the rest of us should just prepare for 4 more years of Donny Cheetoface because they will likely lose again.
