Maintaining momentum in a savage battle for the Democratic presidential nomination campaign is tough, but the load is lightened a little when the who’s who of entertainment come out in implicit support. A music video entitled “Yes we can” based on Barak Obama’s rousing speech soon after losing the New Hampshire primary, is currently spreading like wildfire on the web. Written by will.i.am of Black Eyed Peas fame and Bob Dylan’s son, Jesse, it features a host of celebs (including Scarlett Johansson, John Legend, Herbie Hancock, Kate Walsh, Kareem Abdul Jabbar, Adam Rodriquez, Kelly Hu and Amber Valetta) giving a rousing call for change. It is electioneering at its Web 2.0 best. South African politicians, watch and learn!!
