I'm sure Brexit is going to be a cautionary tale for decades to come on the risks of exiting a well-established union in favor of sticking out on your own.

And there's no unity in the party, either. A California democrat could have more in common with a Missouri republican than his same-party counterpart. The democratic platform this year includes a number of promises that the presidential candidate does not agree with. The republicans did not publish a platform this year. It's essentially a directional signal more than any concrete unifying measure, a party-for-all-people-except-the-ones-we're-against.

If the democrats and the republicans are supposedly holding the union together, they're doing an absolutely awful job at it.
