Though President Obama and Governor Romney will be spending the next few weeks outlining their vast differences, both of them share something in common that makes them unlike nearly 70% of presidents since 1877. It’s not their fiscal, foreign, or family policies. And no, it’s not even their faith. Unlike Garfield, the Roosevelts (Teddy and Franklin Delano), Taft, Wilson, Kennedy, Reagan, Bush (I and II) and many more—neither Obama or Romney were members of a fraternity.
