"We should keep in mind that just over 51 percent of all eligible voters cast their ballots in this election, an all time low. This would mean that, realistically, around 25 percent of all eligible voters voted for Bill Clinton. Of this 51 percent, VNS established that:
About 53 percent of those who voted had reservations about the candidate that they supported.
About 47 percent of those who voted for Clinton had reservations about him.
About 53 percent of all voters think Clinton is dishonest. About 59 percent of all voters think Clinton has not been honest about his Whitewater dealings.
About 29 percent of those who voted for Clinton think he has lied.
