The following comments are from an article in The New Yorker from January 30, 2017. Unfortunately the article is still extremely relevant.

The article reports:

Calling it a “medical mystery of the first order,” scientists are baffled by the ability of Senate Majority Leader Mitch McConnell and House Speaker Paul Ryan to stand upright without the benefit of spines.

Doctors at the University of Minnesota Medical School, who have been studying the skeletal structures of both Republicans for months, believe that their ability to stand, walk, and even break into a brisk trot when confronted by reporters’ questions is “virtually inexplicable.”

“The fact that they can do these things without the aid of spines makes McConnell and Ryan anomalies in the animal kingdom,” said Dr. Davis Logsdon. “According to everything medical science teaches us, their bodies should be collapsing to the ground in two heaps.”

…Logsdon said that the anatomies of McConnell and Ryan require further study, and that there was growing public support for both men to be dissected.

There is nothing I can add to this!
