Why does Obama continue to lie about his and Pelosi's health care bill?

First it was "it won't cost you a dime", Obama said, then no death panels which turned out to be a lie then it was no rationing which was another lie then cuts in Medicare/Medicaid Obama again lied about now coverage for illegal aliens. When will the lies stop? Just today the Senate Finance Committee refused to take abortion funding out of Obama/Pelosi health care bill! Lies, Lies, and more Lies!
