Republicans looking to regain House supermajority

Republicans only need to win one of three special elections to regain a two-thirds majority in the House to override vetoes.

About 50 contested primaries are being held to determine nominees for the Missouri Legislature.

Three special elections also will fill vacant state House seats and determine whether Republicans hold a supermajority.

The winners of Tuesday's special elections likely will be sworn into office in time for a Sept. 10 session when lawmakers consider whether to override Gov. Jay Nixon's vetoes.

Republicans are favored in two of the three special elections.

They only need to win one to regain a two-thirds majority in the House that would allow them to override vetoes without needing any Democratic votes. Republicans already hold a two-thirds majority in the Senate.

The winners of Tuesday's legislative primaries will advance to the November elections for terms that will begin next January.
