CNN has not called the race for Trump but has him leading at 46% in exit polling. Mississippi is a proportional state with 40 delegates in the balance. It definitely looks like Trump is going to have the thing in a walk, more's the pity.
In equally bad news, Hillary Clinton has won in Mississippi. It is also proportional for Dems and they will both get delegates. I say bad news because this means people are still voting for Democrats for some reason. (Trump.)
RedState will be on top of the results as the evening goes on.
