Ancedotal evidence
My parent’s are in their 80’s and live in a retirement home in New England. Most people there are life-long Republicans with backgrounds in the corporate world. They of course lived through WWII. They overwhelmingly favored the Afghanistan bombing because 9/11 understandably reminded them of Pearl Harbor – my Dad included.
I asked him today what the consensus in the retirement home was towards Bush and an Iraq War and he said he couldn’t think of a single person favoring it. No one. Not even the die-hard Republicans.
