Obama derangement syndrome reaches the conservative mainstream?

The over-the-top reactions of some liberals to George W. Bush's presidency earned the label 'Bush Derangement Syndrome'. I think it's time to diagnose a conservative equivalent: Obama Derangement Syndrome. We've seen signs of it in the video Kanishk posted a few days ago, and in the McCain supporters calling Obama a terrorist and Arab. But what's more startling is its spread to the conservative mainstream. If you have the time, take a look at The Corner at National Review Online - a blog populated by the most prominent journalists from the American right's most widely-read, well-respected journal. On it, you'll find the likes of Andy McCarthy speculating that the real author of Barack Obama's autobiography Dreams From My Father was William Ayers. It really has to be seen to be believed.
