Joe Donnelly appeals to Lugar supporters

SOUTH BEND, Ind.-- Richard Mourdock will face off against Congressman Joe Donnelly, in November.

The South Bend Democrat appealed to Lugar supporters, on Wednesday.

Many Republicans said that they are disheartened by Mourdock's primary win and will cross party lines, to vote for Donnelly.

Donnelly said, "When you see the things Richard Mourdock did. He tried to destroy the American Automotive Industry.  He tried to destroy in our part of Northern Indiana, the lives of thousands and thousands of people in Kokomo."

Republicans need to pick-up four seats to regain control of The Senate.

The Democratic Party has promised to pour money into the November election, to help Donnelly win.
