WASHINGTON — President Obama surrounded himself with taxpayers on Wednesday to pitch his plan to preserve current rates for the middle class and raise them for the wealthy. A day before, he met with small-business owners for the same purpose. On Friday, he plans to fly to Pennsylvania to tour a factory to make the same point.

As the president and Congress hurtle toward a reckoning on the highest federal budget deficit in generations, Mr. Obama says he wants a “balanced” approach to restoring the nation’s fiscal order. But the high-profile public campaign he has been waging in recent days has focused almost entirely on the tax side of the equation, with scant talk about his priorities when it comes to curbing spending.

Mr. Obama has embraced specific cuts to the federal budget in the past and has committed to an agreement with Congress that will include deep reductions in spending. But it would be easy for those who listen to his public pronouncements lately to miss it. In public statements since his re-election, he has barely discussed how he would pare back federal spending, focusing instead on the aspect of his plan that plays to his liberal base and involves all gain and no pain for 98 percent of taxpayers.

Republicans and even some Democrats have expressed frustration that Mr. Obama has avoided a serious public discussion on spending with barely a month until deep automatic budget cuts and tax increases are scheduled to take effect. While the president’s aides said it was important to engage the public on taxes, others say he has not prepared the country for the sacrifice that would come with lower spending.
