Mississippi congressional candidates face the challenge of attracting voters for party primaries that follow the long Memorial Day weekend. Polls will be open 7 a.m.-7 p.m. Tuesday.
Voters will be greeted with a sparse ballot, only one race in each of the four U.S. House districts.
None of the incumbents will be listed because they don't have primaries. Only their opposite-party challengers are being chosen.
Republican primaries are being held in the 1st, 2nd and 4th districts, and a Democratic primary is in the 3rd.
If runoffs are needed, they'll be June 22. The general election is Nov. 2.
