Probably all of them, but a few would be tough.
Teddy in my mind would be very tough. Dudes that did all the stuff that he did are just naturally strong and tough, you'd pretty much have to KHTFO for the fight to be over.
Gerald Ford was a big guy. LBJ, get a couple of whiskeys in that dude and he's another, fights not over until he's out cold guy.
I think Ike would have been another very tough out.
W, no problem, but his dad, wiry.
