Sadly, I think Schaeffer is undoubtedly right.
As someone who appeared numerous times on the 700 Club with Pat Robertson, as someone for whom Jerry Falwell used to send his private jet to bring me to speak at his college, as an author who had James Dobson giveaway 150,000 copies of one of my fundamentalist "books" allow me to explain something: the Republican Party is controlled by two ideological groups. First, is the Religious Right. Second, are the neoconservatives. Both groups share one thing in common: they are driven by fear and paranoia. Between them there is no Republican "center" for you to appeal to, just two versions of hate-filled extremes.
The Religious Right supply the kind of people who at McCain and Palin rallies were yelling things such as "kill him" about you. That's the constituency to which your hand was extended when looking for compromise on your financial bailout bill.
There's only one thing that makes sense for you now. Mr. President, you need to forget a bipartisan approach and get on with the business of governing by winning each battle. You will never be able to work with the Republicans because they hate you. Believe me, Rush Limbaugh and Ann Coulter are the norm not the exception. James Dobson and the rest are praying for you to fail.
The president is obviously an open, generous, gracious human being. These days I'd rather he would be a bit more suspicious and cynical.
