He’s not happy about the current actions of his fellow Party members:
I can’t shrug off this flight from reality and responsibility as somebody else’s problem. I belonged to this movement; I helped to make the mess.
I’ve had conversations that felt like what he describes in the beginning of his essay, where I tried to tell a Republican just why the GW Bush administration was a bad thing, and was patronized as being deranged.
In another essay, that he links to in that one, he talks about when he became aware that something was going wrong with his Party:
I moved to Washington, D.C., in 1996. And there I began to notice something disturbing. While the congressional victory of 1994 had ceased to produce much in the way of important conservative legislation, it sure was producing a lot of wealth for individual conservatives. They were moving from the staff offices of Congress to lobbying firms and professional associations. Washington (to quote something I’d write later) began to feel like a giant Tupperware party, where people you had thought of as friends suddenly seemed always to be trying to sell you something. Acquaintances of mine began accepting all-expense-paid trips to the South Pacific from Jack Abramoff.
