WASHINGTON  In the legislative blueprint that Republicans hope will serve as a roadmap to winning control of the House, they declared their two highest priorities to be creating jobs and stopping “out-of-control spending” by the federal government.

“To create jobs, we need to end the uncertainty for job creators and the spending spree in Washington,” the House Republican leader, John A. Boehner of Ohio, said on Thursday at a hardware store in Sterling, Va., where the party unveiled its agenda.

The approach Mr. Boehner set out is based on a belief that smaller government, lower taxes and less regulation will fuel economic growth, create jobs and ultimately lead to a more prosperous nation. It deviated little from the tenets of mainstream conservatism over the last generation.

But even conservative-leaning budget and policy analysts said that the Republican blueprint, as drafted, would lead to bigger, not smaller, deficits and that it did not contain the concrete, politically difficult steps needed to alter the nation’s fiscal trajectory.
