“I am looking forward to reaching out,” President Barack Obama said Tuesday night after he had won reelection, “and working with leaders of both parties to meet the challenges we can only solve together.”

The progressive community must understand this and put aside its rigidity to help him meet this goal. As Obama also said early Wednesday morning, “We’ve got more work to do.”

Yet a network of liberal groups, on Thursday, plan to demand a national day of action against a balanced, grand bargain that could pull the nation back from the fiscal cliff it faces. The beef of this progressive coalition is that a real budget deal would almost certainly cut Medicare spending and may possibly include a proposal to make Social Security solvent through the century.

The president and members of Congress must now begin working to find a solution to the scheduled tax increases and spending cuts that form the fiscal cliff. This is the wrong time to draw ideological lines in the sand.

Both the right’s Tea Party-driven campaign against any new revenue and the left’s pledges to circumvent any changes to Social Security and Medicare could keep us from a balanced deal. This could doom our ability to address the fiscal cliff and secure our nation’s future.
