LOS ANGELES (AP) - Tuesday's elections strengthened the political grip of Democrats in California, and Republicans in the Legislature are in danger of becoming mere spectators at the statehouse.

Democrats hold the governorship and every other statewide office, and they gained even more ground in congressional and legislative races.

In the Legislature, the party secured a supermajority in one, and possibly both, chambers as votes continue to be counted.

Meanwhile, Republican registration has dipped below 30 percent.

Republicans searching for a new direction after Mitt Romney's defeat will question why President Barack Obama rolled up more than 70 percent of the Hispanic and Asian vote, and 9 of 10 votes among blacks.

Demographic shifts have shaped California elections for years, lifting Democrats while Republicans have been pushed to the margins in many areas.
