I'm not concerned about the fact that the election was close.
I'm concerned that, post election, the country is so deeply polarized. For the first time in my life, I fear there's a small but real chance that we're headed for civil war.

Though, as he absorbed Kennedy into his government, I would argue his current leadership gained 50.29% of the votes.
