The Big Tent Is More Like The Big Top
A. Barton Hinkle writes at reason:

Remember when pundits accused the GOP of abandoning its big tent--the one big enough to include a broad diversity of views? You can kiss that meme goodbye. This year's presidential candidates span the political spectrum. They are both pro-abortion and anti-abortion. They have both embraced and opposed bans on assault weapons. They have both accepted and rejected the idea of human-induced climate change, both promoted and derided a government takeover of health care, supported both amnesty for illegal aliens and building a giant wall on the border.

And that's just Mitt Romney. We haven't even touched on the rest of the field yet.

Of course, the candidate a reasonable person would vote for -- Gary Johnson -- is outside the tent altogether and is desperately in need of a charisma transplant. (Do they helicopter that from hospital to hospital in a little cooler?)
