That 49.8% is misleading - it implies that 49.8% of the country support him, but it counts only the votes that were actually cast. He only got votes from about 30% of eligible voters.
Of course we can't know who all those non-voters wanted to win, but I'd rather not imply that nearly half of all americans voted for him.
You read that in Michelle Obama's voice? Weird.
....sorry. it's women's history month and all.
