ST. PAUL — The field is set for a special election to a state House seat in east-central Minnesota that became open in a game of political musical chairs.

Mora teacher Ayrlahn Johnson and Hinckley farmer Nathan Nelson will face off in a Republican primary March 5. Nelson won the GOP endorsement Tuesday night.

The primary winner will face the Democratic-endorsed candidate, Hinckley City Council member Tim Burkhardt, in the March 19 general election.
