A new study claims something like that:
As polls closed on election night, researchers at Duke University and the University of Michigan had 183 men and women chew gum and spit into test tubes and analyzed their hormones.
A few hours later, as Barack Obama supporters began celebrating, they tested hormone levels again, and then later, at two more intervals.
Men who voted for Obama maintained stable testosterone levels, while men who voted for McCain saw those levels drop more than 25 percent.
Or maybe Barack Obama depletes the testosterone levels of conservative young men.
