You don't get it.
Your party has had their brains co-opted by decades of propagandistic bullshit from the right wing informationsphere. This isn't about liberals getting their message out. These bots are explicitly aimed at riling up the deteriorating minority of brain-drained rightwing nutjobs that are fully primed and salivating to swallow anything that confirms their assumptions of the world around them.
These bots, which are real and you aren't even denying it now, after spending the previous two years denying it, aren't talking to liberals. They are here to give your brood a sense of community and numbers. They flood social media and the only people that like, share, and distribute these fake posts as actual information are rightwing nutjobs like yourself, sp33dy, OrroRororor, boomerang, et al. You guys ate this shit up for years, denied it angrily, yet now accept it but blame the liberals anyway.
The only people actually listening to these obvious bots is you.
