Testosterone levels of men who voted for McCain dropped

Researchers found that male McCain voters experienced a drop in testosterone after the tribe leader they were backing lost the election.

"The findings indicate that male voters exhibit biological responses to the realignment of a country's dominance hierarchy as if they participated in an interpersonal dominance contest," wrote the researchers, whose paper appeared in the PLoS ONE peer-reviewed journal.

The present study investigated voters' testosterone responses to the outcome of the 2008 United States Presidential election. 183 participants provided multiple saliva samples before and after the winner was announced on Election Night. The results show that male Barack Obama voters (winners) had stable post-outcome testosterone levels, whereas testosterone levels dropped in male John McCain and Robert Barr voters (losers). There were no significant effects in female voters.
