WASHINGTON (AP) Democrats have moved to within one or two seats of retaining control of the Senate, winning in Hawaii, Washington, and California.

Rep. Maize Hirono won an open seat Tuesday in Hawaii, Maria Cantwell won another term in Washington and Diane Feinstein won re-election in California.

Democratic Rep. Joe Donnelly won a seat the GOP had held for decades in Indiana, beating back a challenge from tea party favorite Richard Mourdock. And Elizabeth Warren won a Senate seat held by GOP Sen. Scott Brown. Republicans also lost a seat to independent Angus King in Maine, a former Democratic governor whom GOP supporters had targeted for defeat.

As of 11 p.m. Democrats had locked up 49 seats, including independent Bernie Sanders. Democrats now hold a 53-seat majority, including Sanders and another independent.
