This is a major setback for the Georgia-based portion of the Democrats' attempts to interfere in the upcoming election. Democrats know lawfare is the only way to stop Trump's return to the White House. However, the appeal of McAfee's disgraceful decision to leave Willis on this case will now be heard late enough that Democrats' plans for a pre-Election Day trial are squashed.
This may appear to be a victory for Trump, however, even he must know that if he wins the presidency, he'll be able to dismiss the federal criminal charges against him in other cases — but not the Georgia case. He could be put on trial during his second term, creating the type of constitutional crisis he warned about years ago when he suggested Hilary Clinton shouldn't be allowed to run for president.
