(CNN) - Are some of Mississippi's Republicans trying to cause mischief? Thirteen percent of the voters in today's Democratic primary identified themselves as Republican; they voted for Clinton, 78 percent to 22 percent. And 37 percent of the Democratic primary voters have a favorable opinion of John McCain; this group also went for Clinton, 62 percent to 37 percent.
Earlier this month, conservative radio host Rush Limbaugh told listeners that since the Republican race was all but over, they should turn out for Clinton, because of his view that she would be a weaker fall opponent for presumptive GOP nominee John McCain - but there is no statistical evidence to indicate his instructions played any role in the Mississippi results.
