Q: "Who coordinates all of that and how do they do it?!"
A: Moveon.org etc...
Weak answer
Deny it if you want but these are /exactly/ the kinds of groups that organize this sort of shit, always have, always will.
I won’t deny it because I have no way of knowing. Same goes for you. So if you going to try and make the accusations you should be able to back them up with something that makes sense... more than a one word answer.
Ah, clearly I've misjudged your intelligence, my apologies. Let's try again, this time I'll explain for ya, and what the hell I'll even give ya a little more to chew on:
Q: "Who coordinates all of that and how do they do it?!"
A: Political groups would coordinate these kinds of opposition attacks. They often pay for buses to get voters to the booths, or even to get protesters on the streets. Protesters have also been paid by such organizations for their participation on numerous occasions - advertisements looking for protesters have been found as well (I believe the last one I saw was paying $15/hour.) Some have argued that the protesters are not "being paid" but rather that the organizations are paying their fees and bails - this supposedly was the case when the Kavanaugh protesters were arrested in the hearing just a few weeks ago. Considering this, it is not at all unfathomable that political organizations would be paying for "victims" to come forward in the same manner - be that paying them outright, or "just" paying their fees to do so. Not that it even requires payment for some folks, in other sexual assault and rape accusations we've had cases where women simply wanted attention.
As for the organization part; one could look at the political groups that were organizing and funding the violence of ANTIFA. It's not very hard to troll social media for folks willing to say something bad about Kavanaugh - especially when the far left not only absolutely hates Kavanaugh because of the lies the MSM has told them (aka he'll overturn Roe vs Wade!!!) but has also completely lost their grip on reality the past couple years; to the point of silencing any conservative views in colleges, mob reporting conservative YouTube and Twitters to get those folks banned, enacting violence upon folks attending Trump rally's, mobbing and harassing anyone that works for Trump in public (I hear they harassed Cruz at a public restaurant just yesterday,) a teacher brought a gun into their school and shot themselves in the foot to protest the 2nd, a lefty shot up a baseball game trying to kill republicans. You cannot tell me that you don't see that some of these folks are unhinged and acting stupid because of the MSM's bullshit riling them up... Given all that, how is it at all difficult to believe that some folks might lie for "the political cause"?
