Obama At The Tipping Point?

From virtually all directions we're learning that the last ten days have been tough ones for Obama. Today, the blogosphere is alive with analysis pointing to serious and unsettling consequences. Here is a taste of the rhetoric:

I don’t know what the political effect of all this will be. But intellectually, this is the week where Barack Obama jumped the shark. In a deep, fundamental way, he is no longer a serious man. Nor an honest one. His public words are now purposefully bleached of truth. And that is a painful thing to have to say about an American president.

Forty years ago, we had another president burdened with unpopular policies and wrapped in self-deception. Nixon turned to alcohol and wandering the White House halls late at night talking to paintings.  Months later he resigned rather than face certain impeachment. Today's political scenario will likely follow a far different track. Regardless, if the past week is any indication, it will be very rough going. Glen Reynold's Instapundit post has more on the story.
