The Twitter primary: Rick Santorum

Rick Santorum Wordcloud 8-1 640

Santorum’s controversial views on gay-marriage and his outspoken manor on the subject have drawn praise from the right and criticism from the left.

A firmly grounded and unwavering conservative, Santorum continues to hold a spot among the field, although his draw may weaken as the primaries move to less conservative states.
