He is a classic creature of the political world: The centrist who finds middle ground on any issue, no matter what the merits of the opposing arguments are. Worse, the centrist often prides himself on being the only adult in the room, his unerring ability to find the precise center of a debate evidence of a maturity beyond the comprehension of callow partisans.

Centrists obviously drive some very smart people nuts, like The New York Times' Paul Krugman. And sometimes compromise really isn't best, as evidenced by a series of tweets trending under the hashtag #CivilWarCentrists. Enjoy.
