STEPHANOPOULOS: The president's lowest poll numbers yet. Is Obama's second term slipping away? Has he lost control? What will it take to get it back?

This morning, the only show where the White House responds. Tough questions for the president's top strategist.

Plus, Republican Senator Rand Paul in a This Week exclusive.

And the analyst who nailed it in 2012, reads this year's tea leaves. Nate Silver makes his debut on our roundtable.

And that and Rob Lowe plays his presidential hero right here this Sunday morning.

ANNOUNCER: From ABC News, This Week with George Stephanopoulos starts now.

STEPHANOPOULOS: Hello again. One year ago this week, President Obama was coasting toward re-election, now he's coming off one of the toughest weeks of his second term.

Let's start out with our chief White House correspondent Jon Karl with more on that.

So you've got the Obamacare troubles, you've got the NSA spying controversy and now this new book "Double Down" goes inside the campaign of 2012 and shows that even winning campaigns aren't pretty on the inside.

JON KARL, ABC NEWS CORRESPONDENT: That's right, George. And perhaps more disturbing for a White House that prizes secrecy so much, is how apparently some of the president's top aides leaked so much information to authors of this book.

(BEGIN VIDEOTAPE)

KARL: In the president's weekly address, no mention of Obamacare or veep switches.

BARACK OBAMA, PRESIDENT OF THE UNITED STATES: I want to cut through that noise and talk plainly about what we should do right now to keep growing this economy and creating new jobs.

KARL: Just an effort to turn the page after one of his toughest weeks of his second term. Who would have thought this joke over a week ago on Saturday Night Live.

UNIDENTIFIED FEMALE: Millions of Americans are visiting Healthcare.gov, which is great news. Unfortunately the site was only designed to handle six users at one time.

KARL: Would turn into something of an actual prediction when Friday a congressional committee revealed only six Americans were able to sign up on Obamacare's flawed website on the first day. And with some unable to keep its health plans as the president promised over and over again.

OBAMA: I said this once or twice, but it bears repeating, if you like your health care plan -- if you like -- if you like -- if you like your plan, you keep your plan -- you can keep your plan -- period.

KARL: The oft repeated promise suddenly changed. The president now saying most, if not all, could keep their health coverage.

OBAMA: For the vast majority of people who have health insurance that works, you can keep it.

KARL: Then there are the new bombshells in the book "Double Down" including campaign staffers resorting to an intervention after Obama's disastrous first debate. The president telling them, I don't think I can do this.
