Re-posting here, for those who are struggling to process this news.
This may not be a matter of Team Trump cutting Sidney loose. It could very well be a joint/strategic decision, perhaps even her own idea. This creates a separate track that allows her to pursue the wholesale fraud case (which could take months to litigate), beyond the election certification and inauguration.
This way, even if Biden become president, we have a chance to prove the true depth and breadth of the fraud after the fact, and do serious damage to the Democrats, guaranteeing a massive red wave in '22 & '24.
