Neither of his elections were close. Both Obama and Clinton won by a large margin. What's scary for the Republicans is how razor thin Bush's two wins were. He didn't even win the popular vote in one of those. The last time the Republicans handily won a presidential election was 1988. You can see why people say the Dems have a huge advantage in 2016. Whoever faces Clinton will have a mountain to overcome and it's not because she's a well known figure.
