Obama and social media

Barack Obama is a shrewd politician. At least that's the impression I get from his unique use of social media.
During his election campaign for the run of Presidency, he make full use of the social media by engaging the public through such media. He literally obliterates the boundaries between the public and private spheres as what Habermas has mentioned and uses it to his advantage as he brings the idea of Presidential candidate closer to everyone in the comforts of their house.
Now, when he seeks to get a re-election as the President, he actually make use of the social media again like FB to achieve his political will by garnering political support from his supporters. In this way, he is able to show in specific terms, how much support can he garner throughout his country. Though, it may not be in good in terms of accuracy, it certainly gives him a good gauge / feedback on the policies he might consider changing or his popularity indicator to see if he can continue with his political career.
Amazing isnt it?
