Republican Sen. Ron Johnson's latest attack ad is hitting Democrat Russ Feingold for taking the majority of his campaign donations from people who live outside of Wisconsin, after promising in 1992 not to do that.
Johnson's latest ad released Tuesday comes five weeks before the election. Johnson's campaign says it's part of a "multi-million-dollar ad blitz for the fall" that includes some money from the National Republican Senatorial Campaign Committee. The NRSC announced Monday that it was pulling back on $800,000 in other ads for Johnson.
The new spot contrasts footage of Feingold in 1992 saying the pledge was "for the future" next to him saying recently that it was for that term only.
About 70 percent of Feingold's donations have come from out of state.
