Very few American voters changed their minds during the 2004 presidential campaign, the University of Pennsylvania’s National Annenberg Election survey shows. Just 16 percent of those who voted for George W. Bush said there was “ever a time” when they thought they would vote for John Kerry. And 15 percent of Kerry voters said there was “ever a time” when they thought they would vote for Bush.
Put another way, 84 percent of Bush voters and 85 percent of Kerry voters said they never thought they would vote for the other candidate.
