Ok here are my thoughts on the play in matchups in the Lincoln region.
Obama/Trump: Both pretty big pansies, but Trump did spend some time in a military academy, and while I'm sure it was more of a rich kid doing rich kid school, I'm sure he learned some type of minor combat skills. Height is similar, but Trump has always been "bigger" and Obama has always been skinny. Obama has never had any real athletic ability, so I'm picking Trump to push through the bone spurs, move on, and get clobbered by Abe.
B. Harrison/Polk: Harrison was commissioned a colonel during the Civil War without any prior experience, was only 5'6", and here's an early picture of him:
Looks kinda wimpy. Polk spent a little time in the militia, but had no formal military service. He was 5'8", so another short guy. Honestly, take your pick here. Simply based on the old picture of Harrison, I'm going with Polk in this one.
Q. Adams/Wilson: Both were nerdy bookworms with zero military experience. Quincy did a lot of traveling overseas with his father early in life, while Wilson's father was a minister and he grew up in the South. Wilson had about four inches on Quincy, which is an advantage, but Wilson was also plagued with health issues most of his life, so I don't know if we can say for sure that he was ever really in "peak" shape. I think Quincy gets in close to negate Wilson's reach, delivers some solid body shots, and moves on.
