So Santorum is against women's reproductive rights, which includes contraceptive medication.  In addition to that, he is critical of public education.  Now, if I'm not mistaken, recent statistics indicate a significant amount of women use birth control, and a significant amount of US citizens send their kids to public schools.  Furthermore, these same people vote.  In other words, they are somewhat responsible for electing candidates into the presidency.  I'm not quite sure why his republican supporters think that he is going to be an effective candidate to oust Obama from the White House.
