U.S. Rep. Scott Rigell: “My love for our country eclipses my loyalty to our party, and to live with a clear conscience I will not support a nominee so lacking in the judgement, temperament and character needed to be our nation’s commander-in-chief. Accordingly, if left with no alternative, I will not support Trump in the general election should he become our Republican nominee.” (1 March 2016)

Carlos Guiterrez, commerce secretary under President George W. Bush: “There comes a time when you have to put the country before the party, and this is that time.”
