It's no surprise that the economy was the top issue for Mississippi voters in Tuesday's Democratic primary, but health care still resonated. Just over half the voters surveyed by network exit polls cited the economy as their top concern. But one in five said health care was their number one issue -- the same number as the Iraq war. (We would argue that health cost and coverage can be a component of economic anxiety as well). Voters who cited health as their main concern voted for Barack Obama over Hillary Clinton by a nearly two to one margin (64 to 35 percent).
