As I sit here anxiously awaiting Barack Obama 's VP announcement , I feel less speculatory than usual . CNN is posting on the hour " We still do n't know who Barack 's pick is ! " -- and everyone 's trying to prematurely claim to know who he 's chosen or when he 's announcing .
According to the above context, answer the following question.
What has lead the speaker to be so interested and invested in Barack Obama 's VP pick ?


They are interested in politics , and are looking forward to getting the answer to this question
