As if you needed another reason to root for Duke,

try this one on for size:  Obama roots for the Holes, and dislikes Duke.  From Mike Corey's blog, The Devil's Advocate:

Q: Obama filled out his tournament bracket with Andy Katz again this week, and once again picked UNC to win at all and chose Duke to lose earlier than we Duke fans might have hoped. As a longtime political writer, why do you think Obama–and politicians generally–engage sports like this? How successful do you think it is from a political perspective? And with Obama, how genuine do you think it is–or how genuinely does it come across to voters? 

Harwood: Obviously basketball has been really important in Obama’s life and still is. So no doubt he enjoys it (with help from Reggie Love, as you know). But showing that enjoyment is a good way for politicians to connect with voters on a personal level on topic THEY really care about. BTW, I interviewed Obama very soon after Duke won the 2010 championship. I asked him for a congratulatory high-five and he pulled his hand back at the last second. He later sent the WH photo of that moment with the inscription: “I rarely high-five Duke people.”

Bold is my emphasis.
