I suspect partisans on either side will draw different interpretations from it. But here's another interesting tidbit out of the Mississippi exit poll. The conventional wisdom and to a significant degree the reality in many other states has been that Barack Obama has picked up the lion's share of Republican crossover voters. Not in Mississippi. According to MSNBC's exit numbers, Republicans made up either 12% or 13% of the voters in tonight's primary. And they went for Hillary Clinton by a decisive 3 to 1 margin.
