Shock poll: Fox trusted more than Obama on Obamacare info
The most trusted voice in America on Obamacare isn't the president -- or most of the media, Congress or insurance companies. It's Fox News Channel.
Just 11 percent said that President Obama is the most trusted source of Obamacare information, about half of those who cite Fox, at 19 percent.
Worse for Obama, who has been fumbling over his oft-stated and false promise that Americans will be able keep their insurance under his namesake program, just 35 percent told YouGov.com that they trust his word a lot or some, while 52 percent said they trust him not too much or not at all.
But it is not enough to be able to deliver a good speech. Politics is about delivering tangible benefits to the American people. That is what the Affordable Care Act was supposed to do, and it didn't do it, and the Democrats are going to pay dearly for their leader's failure. For Obama, there is no recovery from this catastrophe, just as there was no recovery for Lyndon Johnson from his credibility gap.
