It would certainly be the sensible thing for him to do. But that isn't really a quality he's known for.
I think right now, he probably hopes he can--with the help of an obviously biased judge--delay and delay. And then next year is an election year, and he's a candidate. If he wins the election, but loses the court case, he can always pardon himself.
I don't think he'd win the presidency. But he'd stop at nothing trying. And we do not need any more of his chaos, greed, and ignorance.
