With five weeks left in the Indiana Senate race, Republican Richard Mourdock is criticizing Congressman Joe Donnelly for supporting the agenda of congressional Democrats and President Obama in a new statewide ad.The 30-second spot continues the road motif of the campaign, and highlights that Donnelly voted for the stimulus package, bank bailout and Affordable Care Act. For most of the general election Donnelly has trumpeted himself as a moderate, but the GOP and Mourdock are trying to undercut that by showing the congressman's ties to Democratic policies nationally.Check it out: A recent poll put the two in a statistical tie despite the fact that Indiana is leaning Republican in both its gubernatorial and the presidential race.As a result, Mourdock is tying Donnelly to Majority Leader Harry Reid, D-Nv., pointing out that he has raised money for Donnelly during the campaign and that his election will keep Reid and the Democrats in control of the Senate.The Mourdock campaign is also going after Donnelly's middle of the road message, and said repeatedly over the past week that he is pretending to be a moderate. In a recent interview with the Associated Press, for example, Donnelly said he would be willing to vote for a Republican as Senate leader.Senate rules, however, would require Donnelly to caucus with the GOP in order to do so. When WFPL asked the Donnelly campaign which party the congressman would caucus with if elected to the Senate, a spokesperson said it would be the Democrats.
