Indiana 8th district Congressman Brad Ellsworth is a superdelegate to the Democratic National Convention. That means he is free to support any candidate for his partys nomination for President, but Ellsworth told a crowd in Evansville Tuesday that hell cast his vote at the Convention for whoever wins the 8th district in the Indiana primary on May 6th. Since Senators Hillary Clinton and Barack Obama are running neck-and-neck, the Indiana primary may actually count. Ellsworths appearance in Vanderburgh County was part of his listening tour of all 18 counties in the district. Ellsworth also had stops in Vigo, Sullivan and Knox counties Tuesday.
