CNN was so sick of Lou Dobbs, it gave him an $8 million severance package to leave, The Post has learned.

"They wanted him out," according to a source.

Dobbs, who a source said had a year and a half to go on his $12 million contract, shocked viewers last Wednesday by announcing he was quitting.

CNN boss Jonathan Klein and Dobbs, 64, had been publicly feuding over the kind of reporting Dobbs was doing on his show -- especially stories about illegal immigration and the anti-Obama "birther" movement, which contends the president was not born in Hawaii and is not an American citizen.
