Possible, but I think he is Hitler in the bunker at this point that still thinks Steiner can come support him in retaking Berlin. By all reports, the entire head of Fidesz was completely and totally blindsided by the loss, they had built so many yes men around them the idea was inconceivable. I think most have realized the music has stopped now, but Orban still hasn’t. I think he still imagines himself leading a glorious comeback. I think him being too egotistical to leave means Fidesz is going to die as everyone else leaves the sinking ship… unfortunately, the most likely lifeboat for them to scurry to is… Mi Hazank, which has already been courting them and is a much more explicitly hard right party. So Hungary may go from having a center right kleptocrat with a milquetoast center left opposition that was toothless, to having a center right [question mark on politics beyond that] with a hard right opposition.

Could be totally wrong, maybe he just steps away and Fidesz remains the core opposition for the right, but there are concerning signs that won’t be the case.
