“He’s certainly become a little more aggressive to stating his opposition to some of the president’s policies,” said Ed Feigenbaum, the editor of the nonpartisan Indiana Legislative Insight.

With the economy at the forefront in the Hoosier state, where the manufacturing base has been decimated, it is unlikely Libya will be a major campaign issue. Mourdock has so far all but ignored foreign policy issues on the campaign trail.

Still, much of Lugar’s time in the Senate has been focused on foreign policy issues.

“The only foreign policy connection,” said Feigenbaum, “is whether Senator Lugar has been too involved in foreign policy issues at the expense of domestic policy ... or whether he’s been the statesman in the Republican Party as needed.”
