DENVER (AP) — In a showdown at close quarters, President Barack Obama and Republican Mitt Romney sparred aggressively in their first campaign debate Wednesday night over taxes, deficits and strong steps needed to create jobs in a sputtering national economy. "The status quo is not going to cut it," declared the challenger.

Obama in turn accused his rival of seeking to "double down" on economic policies that actually led to the devastating national downturn four years ago — and of evasiveness when it came to prescriptions for tax changes, health care, Wall Street regulation and more.

The economy dominated the evening, as it has the race for the White House all year. Pre-debate opinion polls showed Obama with a slight advantage in key battleground states and nationally.
