Who says sex always sells?

More people are following news about the fiscal cliff than the investigation into Gen. David Petraeus, according to a new Pew poll.

Thirty-three percent of Americans are watching the fiscal news debate "very closely," the poll finds, compared to 22 percent tracking news about Petraeus' resignation as CIA director.

The survey was taken Nov. 15-18, five days after the initial revelations about Petraeus' extramarital affair. Google Trends suggests interest in Petraeus peaked Nov. 10, the day after his resignation, and fell sharply after Nov. 13. But more people are still searching for "Petraeus" on Google than for "fiscal cliff."
