Jean Carnahan says she wants to carry on the ideas and ideals of her late husband in the Senate, if Mel Carnahan gets more votes tomorrow than John Ashcroft. Some republicans have talked of challenging her appointment to the Senate if Mel Carnahan wins. But she says can’t believe someone would challenge the will of the people. She was interviewed this weekend on the ABC “This Week” program. So was Senator Ashcroft. He was asked if republicans would launch the challenge. He indicated he had no knowledge of one, but wouldn’t answer the question about whether he thinks a challenge would be legal.
