Unless they start sanctioning the Democrats who also file politically motivated, and frivolous (which is legalese for for without even an arguable basis in law and facts), it will just make everyone mad at each other. The fact that the judge is a Democrat will encourage the feeling of madness.
It isn’t clear that for people to conspire to defeat their political enemies is illegal or actionable (something you can sue over), and it is allowed to bring a novel theory without being fined for being frivolous. Accusing people who appear to being working for a common goal is not clearly a non-conspiracy. The essence of Trump’s claim were for defamation, and he apparently never argued that the people he was suing knew for a fact that their allegations were false (which is an element you need to prove in a defamation claim).
I would predict the judge will lose on appeal, since the courts are overly disinclined to make it easy to claim that law suits involving politicians are frivolous.
