Well, it wouldn't be the first time someone called a political party insane on here and meant it. Still though, the "extreme" position I don't necessarily agree with either as a general rule. For example, the Mayoral primary in 2007 wasn't won by the most extreme Democrat (Nutter). That probably would have fallen to Fattah. Even on the GOP side, it is a case by case scenario. For every tea party candidate that won a primary, how many have lost a primary? Are they likely to be more displaced from the center of their region's position during a primary? Sure, but it doesn't necessarily mean that taking the most extreme positions and being insane is going to appeal to the majority of the party.
