5 things to know about Mississippi's primary

Mississippi is one of the few states this year where voters face a full ballot from governor to state legislators.

But Tuesday’s primary isn’t going to offer them many hot races.

Familiar names of incumbents fill the ballot in the Republican-controlled state and few races are expected to be competitive. More than a third of the legislature — 66 out of 174 seats — is already decided because the candidates face no challengers in the primary or general election, a common trend nationwide. Accordingly, turnout on Tuesday is expected to be low.

But voters do get some choices at the polls Tuesday, including in races for 23 Senate and 48 House seats. The contest for state treasurer, which typically attracts little attention, has become the most expensive TV war so far as a relative unknown, albeit wealthy, attorney tries to unseat the Republican incumbent in the primary.
