My mom and her church groups seem to enjoy Rick Warren and his book "Purpose Driven Life".
On the flip side of your main question about who seem to speak for the Right, is who seems to be speaking for the Left?
Whenever my father wants to belittle liberals, he brings up something that Barbra Streisand or Sean Penn said or did. I of course counter with something Falwell or Robertson said or did.
I, as a liberal kinda guy, do not for a moment think that Streisand speaks for me, and I am just as certain that conservative folks probably feel the same way about Falwell and company.
