The Republican Party is well known for looking, thinking, and acting backwards, but even for them this is a striking (and unflattering) comparison.
John McCain, 2008:
Mitt Romney, 2012:
Hey Mitt, here’s a protip for you: If you can’t stand up to the nutters at your rallies, no one’s going to think much of your ability to stand up to threats to America (especially the biggest threat; namely, YOUR OWN PARTY).
Also, when you can be compared unfavorably to John McCain, you’ve really cranked the FAIL up to eleven and broken off the knob.
