How could a meeting like Trump Jr.’s happen? Easy: Campaigns are circuses.

When I heard of the meeting Trump campaign staffers had with a Russian lawyer last year, like many of my brethren who have worked in campaigns, I was not surprised.

Weirdos and politics go together like peas and carrots: Strange, bizarre meetings. Strange, bizarre people. Clandestine operations. Inexplicable decisions. Things that in the light of day look strange, but in the heat of the moment seem perfectly rational. People often do things in politics that later can’t be explained. At least not always reasonably.

Years ago, an old campaign operative told me, “In politics, you can be an adulter or a drunk. I chose to be a drunk.” Normal?
