GOP super-PAC ad: Donnelly a ‘rubber stamp’ for Obama

The ad then says that Obama “is taking America off a fiscal cliff and running our economy into the ground.”

{mosads}”We don’t need a rubber stamp for Obama’s policies. We don’t need Joe Donnelly,” the ad closes.

The ad is running statewide and has $25,000 behind it, a small but not insignificant total for a radio purchase in the state’s inexpensive media markets.

Donnelly faces Tea Party favorite and Indiana state Treasurer Richard Mourdock (R), who beat six-term Sen. Dick Lugar (R-Ind.) in a primary last week. That race featured more than $4 million in outside spending, most of it attacking Lugar.

Democrats are hopeful that some of Mourdock’s hard-right stances and rhetoric have given them an opening in the race, but Republicans have promised to closely tie Donnelly to Obama, who is unpopular in the conservative state. This radio ad is the first investment in that line of attack.

The group is headed by James Bopp, a prominent conservative attorney from Indiana who has long worked against campaign finance regulations and was an adviser on the Citizens United case that legalized super-PACs.
