*Now America’s number one a-hole has gotten on the last nerve of a California legislator.

State Senator Leland Yee is asking for a boycott of companies that advertise on Rush Limbaugh’s radio show after the conservative commentator refused to apologize for mocking China’s president.

Yee is upset at Limbaugh because on his Jan. 19 radio program, he did a nonsensical impression of Chinese President Hu Jintao’s speech with President Barack Obama.

After Yee complained about Limbaugh’s crude imitation, Limbaugh poked fun at the Chinese-American lawmaker, who’s running for mayor of San Francisco.

Yee told the San Mateo County Times newspaper that Limbaugh’s actions were “extremely hurtful” and damaging for children to hear.

Yee reached out to civil rights organizations Tuesday and launched an online petition asking people to join the boycott.

The lawmaker said he also received a racist threat that was faxed by someone who appeared to be a Limbaugh supporter.
