Newark, N.J. Mayor Cory Booker proved that in his line of business, he works for the people. And with help -- no less -- from social media. Booker has taken to his Twitter account to communicate with Newark residents, snowbound and immobile. And not only has he tweeted at and direct message'd a number of individuals. He's also showed up on their doorsteps, at their cars, and on their streets. The New York Daily News reports.
