This is lame, even by the low bar Jay Carney has set for himself. If there were any doubts in my mind that President Obama lacks authority to unilaterally change the ACA, they were erased by Carney's dismal effort to obfuscate in this response. He asked about the assertion by Democratic Senator Tom Harkin that Obama lacks the authority to delay the law. He goes on a rambling diatribe against Republicans wanting to do whatever they can to stop Obamacare. When he's reminded Harkin is a Democrat, Carney goes all the way off the deep end.
