(Politico) — The politics of the debt fight were a drag for President Barack Obama, yanking his popularity to new lows. Here’s an even bigger drag: Obama emerges from the months-long fracas weaker — and facing much deeper and more durable political obstacles — than his own advisers ever imagined.

The consensus has been that for all his problems, Obama is so skilled a politician — and the eventual GOP nominee so flawed or hapless — that he’d likely be re-elected.

This breezy certitude fails to reckon with how weak his fundamentals are a year out from the general election. Gallup pegs his approval rating at a discouraging 42 percent, with his standing among independents falling nine points in four weeks.

His economic stats are even worse. The nation has 2.5 million fewer jobs today than the day Obama took office, a fact you’re sure to hear the Republicans repeat. Consumer confidence is scraping levels not seen since March 2009.

Obama advisers acknowledge the challenges posed by the economy, but argue that voters will like his rescue of the auto industry, signing of Wall Street reform, championing of new restrictions on credit-card issuers, repeal of “don’t ask, don’t tell,” investments in clean energy and victory on insurance protection for people with preexisting conditions.

Privately, however, Obama’s team is concerned about the factors beyond its control, talking of an imminent need to retool their economic message and strategy heading into 2012. Absent the president’s ability to defy political gravity, one Obama adviser conceded, “The numbers add up to defeat.”
