Rick Perry
John McCain
Carly Fiorina
Lets say you are missing a bigger pattern.
Doug Hoffman
Michelle Bachmann
Sean Duffy (Who scared David Obey out of the race)
Adam Kinzinger (IL-11th)
Rand Paul
Tom Emmer - for Gov. Minnesota
Tim Burns - PA-12th
Maj. Vaughn Ward - Idaho 1st
Lt. Col. Allen West - FL-22nd
And more.. its not that bad a pattern.
The pattern here sadly is my way or the highway. Practicality need not apply.
