Cillizza: ‘The Greatest Thing that Happened to the Republican Party Is Barack Obama’

CILLIZZA: "I always say that the greatest thing that happened to the Republican Party is Barack Obama. Yes, he spent eight years in the White House but during those eight years they have made massive gains. I wrote last year, if you look at the full party, this is assuming Barack Obama in the White House and maybe Hillary Clinton in the White House, the Republican Party is much healthier overall than the Democratic Party."
