At what point does commercial excitement over the inauguration of Barack Obama get ridiculous? I can't pin it down, but I can say that there's a staggering variety of presidential products available for purchase around D.C. And have you seen the new Pepsi campaign? The "Prince of Petworth," a district blogger, snapped a photo of the Obama product he thinks crosses the line: "Obama Marketing Has Finally Jumped The Shark." So, if you're here, are you stopping at every intersection to peruse the wares for sale on the street corners? If not, do you shop the swag stores online and count the days (OK, we're down to one now) till the Inauguration on your Obama calendar? What's the most bizarre piece of presidential paraphenelia you've seen?
