Would
41% seem like a more reasonable number?
And 15% of Democrats according to that poll. And it's a different sort of conspiracy theory than a more complex one involving a party which isn't even in power trying to distract people from Muslim terrorism. That's a theory which you can't buy into out of pure ignorance but instead need to actively research and seek out fellow crazies. It sounds like it would be a fringe even among truthers of this event, like some of the crazier 9/11 theories out there. People buy into different conspiracies for different reasons psychologically.
Well, I think most of the Republican dissent would be about who exactly was responsible for the crime(ie. the dissidents would say it was liberals trying to make right-wingers look bad), not saying the crimes were a good thing.
Why would Republicans associate themselves with neo-Nazis? Remember, most conservatives think Nazis are left-wing and not much different than communists and associate the KKK with the Democrats (and Senator Byrd is still alive as "evidence" for this theory). The only people who associate neo-Nazis and conservatives together are actual neo-Nazis trying to look respectable by calling themselves conservatives (David Duke types) and certain people on the left, which while not entirely wrong, is like associating American liberals with Stalin, Mao, and far-left terrorists like the Weathermen.
OTL had the OKC bombings, neo-Nazi bank robbers, Olympics bombing, and abortion clinic attacks all done by far-right groups, and such theories as to what "really" happened generally stayed out of the mainstream of conservative ideology.
Though post-9/11, you did have a few conservatives saying stuff like
this.
Oh, that would be a thing too obviously.
