The Daily Mail reported Thursday on a study published in the Psychological Science journal suggesting there is a correlation between a man’s upper body strength and his political associations.

According to the research conducted by Michael Bang Petersen of Aarhus University, Denmark and Daniel Sznycer of the University of California, Santa Barbara, men with greater upper body strength are more likely to support self-interested principles regarding redistribution of wealth.

"Despite the fact that the United States, Denmark and Argentina have very different welfare systems, we still see that — at the psychological level — individuals reason about welfare redistribution in the same way," says Petersen. "In all three countries, physically strong males consistently pursue the self-interested position on redistribution."

Additionally, the study found that men with little upper body strength were more inclined to the redistribution of wealth supported by the Obama administration.

The study reveals that natural selection may be a factor in shaping political behavior. 

"This is among the first studies to show that political views may be rational in another sense, in that they’re designed by natural selection to function in the conditions recurrent over human evolutionary history," explained Peterson.

In other words, Republican men know how to "protect this house." In honor of this study we have complied a list of men who prove the research:
