He lost the general election. By over 3 million votes. He won the EC because, for the 5th time in just under 250 years the EC went against the popular vote.
I actually think him leading in the polls is a good thing. I'm hoping that creates an urgency to go out and vote. If he were getting slammed in the polls I'd worry about complacency in voters. Maybe that's just copium on my part though.
