Echoing a similar pledge by Speaker Nancy Pelosi (D-Calif.), House Majority Leader Steny Hoyer (D-Md.) will promise not to let the recent wave of Democratic gains in the House cloud the goal of bipartisanship in the 111th Congress.

“The 33 new Members of Congress coming to Washington to swell our side of the aisle are pragmatic, not dogmatic,” Hoyer plans to say at a National Press Club event on Tuesday morning.

“They were elected on promises of bipartisanship and fiscal discipline. They were elected, quite simply, to solve problems, not further politicize Washington,” Hoyer will say.

Hoyer, who often sides with moderates in his party, will emphasize that Democrats have to lead from the middle if they want to stay in the majority. He will also weigh in on the Republican Party’s search for a way forward after losing more than 20 seats in the election.

Fiscal responsibility also will be a theme in the new Congress, Hoyer plans to say, and will be central to meeting Democrats’ campaign promises on the economy, health care and energy.

“Spending wisely today can save us money tomorrow. That is why our country needs far-reaching proposals, even in this recession. In the broad sense, fiscal responsibility should be at the core of our entire governing philosophy,” he will say.

Hoyer’s remarks mirror those of Pelosi and President-elect Barack Obama, both of whom have vowed to seek compromise in the next Congress. Pelosi spoke at the bipartisan new Members’ dinner on Monday night, similarly pledging that Democrats will find common ground with Republicans to enact major reforms.
