Michael Gerson is one of conservatism's more thoughtful commentators and today he recalls two speeches by then-candidates Bill Clinton and George W. Bush in which they challenged the orthodoxy of their own parties in ways we did not see in Tampa and Charlotte. His article is here. 
Right next to Gerson's op-ed was an article by Robert Kagan on the situation in Egypt and why some of the rhetoric on the right is not only wrong but dangerous. Last night, watching Sean Hannity, I was hoping someone of Kagan's stature would take on this ridiculous anti-Islamic drumbeating, and I am delighted to see Kagan do the job. I should add that Mr. Hannity called in as his expert on these issues - Sarah Palin. Hmmmm. Maybe she can see Libya from her house too.
