We have it on good

We have it on good authority that the reason the Republican Party pulled its ad attacking Mondale’s record as Vice-President is that the party’s own polling, together with an intuitive sense of how the race is going, indicate that Coleman is ahead and momentum is on his side. The party knew that releasing the ad would cause a controversy, and feared the controversy might disrupt the currently favorable dynamics of the campaign. Hence the decision to pull the ad.
