LOS ANGELES – Sen. Barbara Boxer says Sarah Palin's acceptance speech for the Republican vice presidential nomination was “laced with ridicule” and calls the Alaska governor an extremist.

At a Thursday meeting with transportation officials in Los Angeles, the Democratic senator told reporters that Palin's views are “way out of the mainstream.” Boxer said Palin doesn't believe global warming is caused by human activities, is against abortion and opposed to stem cell research.

Palin's speech Wednesday in St. Paul, Minn., combined some of her beliefs, jokes about being a hockey mom, and attacks against Democratic presidential nominee Barack Obama.
