On Tuesday President Barack Obama warned Republicans that there would be no deal without them agreeing to raise taxes on the rich, a stand they have made clear they are loathe to budge from.
But he offered a hint of wiggle room, declining to state that the top income tax rate must go up and permanently remain at the 39.6 percent level seen under the Clinton administration.
"We have the potential of getting a deal done," Obama told Bloomberg TV, adding that Republican proposals to close loopholes and cap deductions would not produce sufficient revenue to make a serious cut in the deficit.

Australia said economic growth eased to 0.5 percent in the three months to September and 3.1 percent from a year earlier, hit by a slowdown in China, but in line with forecasts and soothing worries it could be headed for a hard landing.
