The Wisconsin Democracy Campaign predicts the money spent during the recall election could double the record amount spent in the last gubernatorial election.
Mike McCabe, the Democracy Campaign's executive director, said once the final numbers come in, it is possible almost $80 million may have been spent during the election.
Most of the money went to ads, which McCabe said influences only 2 to 3 percent of voters.
"For the average citizen, it really turns their stomachs, and I swear to God, if airlines advertised the way politicians do, I don't think anyone in America would fly," McCabe said. "But people in the political class are devoted to doing it this way."
If the estimates are correct, spending would shatter the old record for money spent for a gubernatorial race.
