Since he became a republican in October of 1993 and began running for office, he has won a single election (49%), to a single term as a failed governor from 2002-2006, and was forced out against his wishes for reelection, leaving with 34% approval.
How does such a small time bit player come to dominate the national republican party?
Because the lo-info republicans see him as 'viable'. He won election once.
