Joe Biden Shopping at King of Prussia

This just in. Last Friday, the day before Delaware Senator Joe Biden would be revealed as Barack Obama's running mate, he went shopping at Thomas Pink store in King of Prussia. His purchase: a stark white shirt by Black Label and a sky blue tie by Liquorice Plain. Here is in a pic with Obama. But when I look at it, I can't help but think is this a Presidential looking group to you? Will Biden be enough to quell people's fears about the capability of the Illinois Senator? Was this red/blue tie combo planned or an unfortunate fashion coincidence?
