Dems couldn't stop ACB being nominated, but they could have stood and screamed 'This is a sham. We don't live in a Democracy. Our institutions are a failure.' which would have titled public opinion away from ACB among Dems.

Now the dumb thing is expecting Dems to do anything different. Worshipping institutions is what they do. At least it's starting to make some younger libs question party leadership. I'm slowly radicalizing some family and friends by pointing out that Dems have no interest in fighting let alone winning.
