Quote - I think Americans are becoming increasingly fed up with the extremes and excesses of the right.

I actually would agree with you on the backlash against extremes of both left and right, though I quote only this part because that's the only one I can offer a concrete example to support.

Westboro Baptist Church (and I use the term "church" very loosely) and the backlash - not just the Patriot Guard Riders, but more visible community counter-presence when those loonies are out and about.
