(CNN) - Party lines in the sand deepened Saturday as Democrats and Republicans used their weekly addresses to demonstrate unity over wanting a stronger economy and differences over how to achieve the goal.
Echoing the debate on Capitol Hill, GOP Sen. Mark Kirk of Illinois voiced support for extending all of the Bush-era tax cuts, while Vice President Joe Biden said tax cuts should be extended only for middle class Americans, or those making under $250,000 a year.
"The current leaders in Congress should not move forward with plans that were just rejected by the American people," Kirk said in the Saturday radio and video address. "These leaders should not raise taxes and risk another recession. Instead, Congress should reduce spending and prevent another tax hike on American taxpayers."
Kirk said failure to extend the tax cuts that are set to expire January 1st hurts the entire economy and means taxpayers, small businesses and investors face economic uncertainty.
Biden agreed that Congress should act, but said tax cuts should only be extended for "middle class families" to ensure the economy continues to grow.
"After a decade in which they lost ground, middle class families can ill-afford a tax hike – and our economy can't afford the hit it will take if middle class families have less money to spend," Biden said Saturday.
Both men also took aim at other legislation that recently failed in Congress.
The vice president expressed disappointment that benefits have not been extended for unemployed Americans, calling it "bad economic policy" and "just simply wrong."
Kirk said Congress should end the use of earmarks, legislative provisions that direct approved funds to a specific project. He called the bill's failure "disappointing" and said Senate Democrats - who overwhelmingly voted against the bill - "disconnected from the American people."
