“It’s about the independents. The folks in the middle still could decide it,” said former Indiana GOP Chairman Murray Clark, who first met Lugar working for his failed 1974 Senate campaign. “That group of people can be a big factor in the election and the more they can hear from Dick Lugar in support of Mr. Mourdock I think can be helpful.”…

Mourdock was “touched” when Lugar graciously introduced him at a Senate Republican caucus lunch at the Capitol before the August recess, campaign spokesman Brose McVey said. And he refused to rule out the possibility the senator could assist Mourdock in the closing weeks of the campaign.

“There is ongoing contact,” McVey said. “The jury is still out as to where this will take us.”
