INDIANAPOLIS (AP) — Senate Republicans are jumping into Indiana's Senate race with a new ad, outdoing a recent buy from national Democrats as the parties battle for control of the Senate.
The National Republican Senate Committee is spending $650,000 on an ad that will run statewide on broadcast and cable for one week starting Tuesday. A Republican Party source tracking ad buys confirmed the new spot on condition of anonymity because it has not aired yet.
The NRSC buy surpasses Senate Democrats, who are spending $516,000 on a spot airing at the same time.
Spending in Indiana has quickly escalated as Democratic candidate Joe Donnelly has stayed neck and neck with Republican Richard Mourdock since May. Mourdock's primary victory over Sen. Richard Lugar created the opening for Democrats in Indiana.
