Missouri Republicans have increased their control of the state Legislature, apparently claiming the two-thirds majority needed to override the governor's vetoes.
Complete but unofficial returns show the GOP apparently will have 110 seats in the 163-member House. In the state Senate, Republicans maintained their veto-proof majority. But incumbent GOP Sen. Jim Lembke, of St. Louis, lost to Democratic challenger Scott Sifton.
Several sitting House members also lost their re-election bids.
State lawmakers were competing for the first time in redrawn districts based upon population changes from the 2010 census.
