It's pretty obvious the word "conservative" means something different to the editors at the London Telegraph than it does to me. As I read through the list, it was readily apparent that they recognize no distinction between real conservatives and neocons- and, as evidenced by their choice as the most influential "conservative" in the United States, they don't know the difference between a liberal and a conservative, either.
Their choice as the most influential conservative? Rudy Giuliani. That's right, a pro-gay, pro-abortion, and pro-gun control liberal is the most influential American conservative.
The failure to distinguish notwithstanding, the ratings themselves are laughable. I don't like Bill O'Reilly, but having him at #82 and Glenn Beck at #18 is patently absurd. Ron Paul made the list at #96, with Chuck Norris checking in 25 spots ahead of the Congressman.
The liberal list is a little more feasible, but George Soros at 15 is insane. Through his MoveOn.org and other progressive/socialist organizations, Soros basically controls the Democratic Party. At least they put Ah-nold on this list- although I'm not sure why Lieberman is listed among the Conservatives.
For a good laugh, you can see both lists in full here.
