Smith will use this to appeal Cannon’s decisions in the pretrial motions to the court of appeals, asking for her orders to be reversed. Smith may use this as a lever to have the appellate court remove Cannon from the case.
Quite possible - but unlikely. The whole purpose of delaying the trial charges for two years was to interfere with the election. A delay, and anticipating a Trump win in November, renders Smith's whole effort pretty much moot. To wait until after Trump's presidency to re-charge would be a pointless vindictive scheme.
The thing to bear in mind in all this 'lawfare' is the obvious goals our enemies have in mind for America manifest in their present autocratic overthrow of all that has been considered legal and common. They know that Trump plans to negate their whole reason for ripping everything apart - as he did in his first term.
Their paranoid fear and intensive hatred is obvious in their every questionable word and action.
