Chamber of Commerce endorses Lugar

"With small businesses in Indiana and across the nation facing prolonged uncertainty over rising energy costs, pending regulations and the threat of new taxes, we need leaders in the United States Senate who will fight through the gridlock," he continued. "Senator Lugar is a demonstrated leader who has shown his commitment to protecting and advancing the interests of Indiana's job creators."

While the endorsement from the center-right, pro-business Chamber isn't a surprise, if the group spends heavily for Lugar it could make a difference in his May 8 primary.
