A Democrat and a Republican are vying for a seat in the Minnesota House of Representatives in a special election that could leave the chamber tied or give Republicans a slim majority. A Democrat won the seat by 30 percentage points last November, but a judge later ruled that he did not meet the residency requirements to run for the office.

Democrat David Gottfried won the special election for a Twin Cities metro state House seat, returning the Minnesota House to a rare tie, according to unofficial results from the secretary of state's office.

An existing power-sharing agreement reached last month will keep a Republican speaker in power in the state House.

Republicans in the Minnesota House lost a one-seat edge in the Capitol, where tensions over party dominance have simmered for weeks.
