Difference between state charges and federal charges

The main difference between state charges and federal charges is the absence of presidential pardon power for state convictions. In the case of the former President Trump's indictment in Georgia, if he and his co-defendants are convicted, there will be no possibility of a presidential pardon. This lack of pardon power could potentially be a game changer for the case. Moreover, having multiple co-defendants, including individuals who worked for the administration, increases the chances of someone cutting a deal with prosecutors and providing incriminating information against others.
