The percent motivated by animus is the number of votes lost due to animus divided by the total number of whites who would have supported a Democrat absent prejudice. Section III.B. finds that turnout was unaffected, on average, by prejudice. Thus, the denominator (the percent of whites who would have supported a Democrat, absent prejudice) is the number of whites who supported Obama plus the number of votes lost due to prejudice.
Exit polls suggest 41.7 percent of 2008 voters were white Obama supporters. The percent motivated by animus is estimated between 3 = 6.7 and 5 = 10.7 percent. Between 6.7 and 10.7 percent of white Democrats did not support Obama because he was black.
also you can look up the search data yourself and make your own conclusions. you can read the paper and decide if the algorithm is a good one as well.
