There's an excerpt from John Dean at Salon that deserves reading. His new book is called "Broken Government," and it details how the GOP has changed beyond anything he recognizes.
Go read the article. Then go read Altemeyer.
As I was writing this closing section an old friend from the Nixon White House called. Now retired, he is a lifelong Republican who told me that he voted for Bush and Cheney twice, because he knows them both personally. He asked how my new book was coming, and when I told him the title, he remarked, "I'll say the government's broken." After we discussed it, he asked how I planned to end the book, since the election was still a good distance away. I told him I was contemplating ending midsentence and immediately fading to black -- the way HBO did in the final episode of the Sopranos, but that I would settle for a nice quote from him, on the record. He explained that he constantly has to bite his tongue, and the reason he does not speak out more is because one of his sons is in an important (nonpolitical) government post, and we both know that Republicans will seek revenge wherever they can find it. How about an off-the-record comment? I asked. That he agreed to.
"Just tell your readers that you have a source who knows a lot about the Republican party from long experience, that he knows all the key movers and shakers, and he has a bit of advice: People should not vote for any Republican, because they're dangerous, dishonest and self-serving. While I once believed that Governor George Wallace had it right, that there was not a dime's worth of difference in the parties; that is not longer true. I have come to realize the Democrats really do care about people who most need help from government; Republicans care most about those who will only get richer because of government help. The government is truly broken, particularly in dealing with national security, and another four years, and heaven forbid not eight years, under the Republicans, and our grandchildren will have to build a new government, because the one we have will be unrecognizable and unworkable."
