They are in court. If they make false statements they get thrown out of court. That doesn’t undermine the electoral system. That sustains it.Sorry, you have this completely backwards. Trump and his people are making false statements to undermine the system.
And the courts will decide the veracity of the claim.They are now saying that the GOP governor of Georgia is involved in the conspiracy, and may have taken bribes (or given them depending on which conspiracy they are using at the moment).
And if they lack evidence, the courts will dismiss this.They are alleging massive international conspiracy
What more do you want? Really, what do you want to see done? Should he be arrested? Not allowed to access the courts? What specifically, and how would that fit into the laws of the land?
You may consider the rhetoric contrary to the system, but it does not undermine it. That’s why we have the courts.That kind of direct attack on our electoral system,
Further, have you cared one bit what Trump has said for four years? Why care now?
