Scott Walker is the new Rick Perry — an under-prepared, shoot-from-the-hip, corporate-fellating rightwing loon. Mike Huckabee is an old, bloated, out-of-touch hinterland yokel. Jeb Bush is a moderate, practical-minded conservative but no way will the country stand for a third Bush in the White House. Ted Cruz is a mischief-making sociopath. Rick Santorum is yesterday’s news. Ben Carson is a distant outlier — the conservative neurosurgeon candidate. Which leaves Rand Paul as the only somewhat tolerable guy in the pack. He won’t win, but at least he warrants respect in some quarters.
