You state:
We hope some of these ’stuck-in-the-middle’ evangelicals will find Centrism and Progressivism appealing.

I would hope the same thing.
It is my belief that, toward this end, they must reject the Democrats’ third way brand of centrism.
And so, the way I call it, the end result will be more moderates in the GOP.

I heard part of an interview with Lincoln Chaffee on NPR a few weeks ago. It was rather revealing.
The number of Republican moderates in the Senate has been shrinking under the Bush administration, and this was no accident.

It seems as if both parties have been struggling for some time to make themselves irrelevant and unappealing.
The both have been driven by the extreme ends of their activist base for too long.

But it’s the independants that always swing elections.
