I wouldn't really say I'm happy. I think relieved is more the right word.
I'm also quite thankful that the margin wasn't as close as last time. 3.5 million votes is quite the number! And I'm amazed by the majority issue. I had no idea that no one has won a majority since 1988. I guess I had assumed that Clinton had gotten a majority both times, but apparently that was a wrong assumption.
So that's where we are.
