The Republicans were much more unified. Only 7 voted against the war, versus 263 who voted for it. Who were those 2% of Republicans who voted against the war?
Sen. Lincoln Chafee (RI), who left both the Party and the Senate.
Rep. John Duncan (TN), the only one still in Congress.
Rep. John Hostettler (IN)
Rep. Amory Houghton (NY)
Rep. James Leach (IA)
Rep. Connie Morella (MD)
Rep. Ron Paul (TX)
A while back, HuffPo did a set of interviews with five of those seven (Duncan and Hostettler were unavailable). It's fascinating to read.
Here's Lincoln Chafee:
"To me, it was about growing up in the Vietnam era and not wanting to go through that again [...] I remember the difficulty the soldiers had coming back here after Vietnam. They had the same issues: PTSD, re-immersion, alcoholism. You have to be prepared to take all that on."
Chafee also didn't believe CIA officials who showed him photos of metal tubes in Iraq and said they were being used to make weapons of mass destruction. He recalled thinking those tubes could have been purchased at a local hardware store and used for a multitude of things.
"More than anything, it was the body language of the CIA that told me it wasn't true," he said.
Smart guy, Chafee.
Ron Paul also thought Iraq was no threat to the US, and (rightly) worried about the cost:
There was no threat to our national security, and also the arguments that they were using [for] why we had to go in, I didn't believe them [...] I could see where it was going to cost us a lot of money, and I kept saying this even before -- it's going to cost us a lot of money, a lot of lives. It's going to go on a long time.
The others among the seven have interesting comments, too.
