I disagree with the premise of your question.
I think Americans have been deceived by the media and the left that paints a distorted picture about Conservatives.
I challenge anyone to tune in to talk radio and just listen to Rush for 3 hours and I am willing to bet they will take away with a different view of Rush Limbaugh. What does that tell you?
They have no clue about what conservatives stand for, only what they have been fed about what Rush said... Usually a distortion.
If anyone is interested in learning about what conservatism is all about, check out my hubs. "conservatism defined" and a few other related hubs.
The other great miss conception is that America is center politically. By most polls, America is 40% conservative, 30% liberal and 30% independent.
The other term "extreme" is also associated with conservatives when in reality, most conservative beliefs are center and common sense.
My suggestion is for you to forget what you've been told about conservatism or conservatives and just go out and find out for yourself. You may just be surprised.
