Without a doubt, yes. Start listening to conservative opinion, on the radio, websites, etc. You will find two factions. One who literally do believe that is a plot: these are the people who listen to and believe Rush, Hannity, Coulter, etc., let's call them "pop conservatives" but they are mostly just paranoid culture warriors. Then, there are the smart conservatives who oppose the taxes and regulations on intellectually defensible reasons of economics and liberty, but usually don't ascribe it to the notion that Obama wants simply to destroy capitalism and kill old people.
Being politically naive, I had NO idea the second faction existed until I started digging for it. This is because the first faction is the current face of the GOP, and gets all the press.
On the flip side, there are equally nutty folks who think Bush started falsified wars to enrich himself and his friends. It may have been a side-effect, but I have no doubt that he *thought* it was the best way to improve our lives.
Pound for pound, conservatives have a lot more batshit-insane people than the liberals do. There's a few liberal kooks on various blogs here and there, but conservative kooks are *everywhere*, 24 hours a day on talk radio. Tune in for 8 hours straight of bashing not just liberals, but anyone who doesn't have the most hard-right stance on ANYTHING! Laura, Rush, then Howie Carr! The conservatives are eating their own babies now.
