If he wants to have a chance I think he will have to. Maybe not appologize to McCain exactly, but just say that he got carried away. Either way, I don't care for Trump so I don't care much what happens to him, he was bound to step in it eventually as that is who he is. Trump is incredibly thin-skinned and can't control himself when he's attacked. Trump was at least being a useful idiot before this and I thought maybe he could actually help get rid of McCain, now idk, hope this won't get McCain sympathy votes.
Part of it is comical though, Trump became flavor of the month and was having a meteoric rise, and then a sudden crash and burn. Of course the crash and burn part is tbd, but I think this is gonna hurt him bad. This may be the quickest rise and burnout ever witnessed haha.
