I also voted for Keyes. More than once.
He was an incredible speaker and a brilliant man. He was actually my first vote (GOP primary CA so 1996 or 1995). A truly impressive man. He fell on his sword vis Obama when Seven of Nine’s husband was revealed as a perv. When his daughter came out as a lesbian and an opponent he disowned her- which I am sure was personally difficult but morally sound- quite different than (I am sure you recall) Rob Portman. It is easy to oppose something when it is wholly alien to you- totallty different moral calculus when its your daughter- I think if there were more Ambassador Keyes and less Mitt Romneys in leadership our nation would be better off.
