Presidential Candidates seek the Support of Uncommitted Superdelegates LAS CRUCES, NM (krwg) - According to the Associated Press, Tuesday's Democratic Presidential Primaries in North Carolina and Indiana helped Senator Barrack Obama increase his lead in the delegate count to 150 over Senator Hillary Rodham Clinton. Obama now needs about 170 delegates to secure the democratic nomination. As KRWG's Marco Grajeda reports, with the race dwindling down pressure is building on the close to 270 uncommitted superdelegates including New Mexico U.S Representative Tom Udall to pick a side. © Copyright 2009, krwg
