Listen here as we look back at an historic year in politics! How did Barack Obama move from second-tier candidate to become the upset nominee of his party and the 44th president of the United States? Did Hillary Clinton make fatal mistakes that ruined her White House bid or was she just defeated by a political phenomenon? How did John McCain come back from the brink of political death to win the Republican nomination? Why couldn’t he win the White House? Was Sarah Palin a plus or minus for McCain? We ask all of these questions to University of Virginia Professor Larry Sabato.
