After Democrats won control of Congress in 2006, their agenda for 2007 was unmistakable. It would start with taking steps to try to end the war in Iraq as well as tackling the items on their “Six in ’06” campaign pledge.

But the plan for the second session of the 110th Congress is unclear. The economy is expected to play a leading role on Capitol Hill this year, while Iraq will take more of a back seat. Democrats are well aware that they do not have the votes to make significant changes to Iraq policy and believe they can attract enough support to enact some sort of an economic stimulus package.

Yet there is much uncertainty in what will be in that bill, especially with a White House that will undoubtedly want something different.

Democrats have made some progress on their Six in ’06 agenda, enacting bills on lobbying reform, student loans and the minimum wage. However, stem cell and Medicare prescription drug negotiation legislation has been and will continue to be blocked by President Bush’s veto power. Those bills, Democrats predict, will be made law in 2009, when they hope to have control of the executive and legislative branches.

There is no shortage of bills to address in coming months, some of which were not completed last year, such as the farm measure, patent reform and reauthorization of the Foreign Intelligence Surveillance Act.

Democratic appropriators, meanwhile, are expected to have more time to focus on their spending bills earlier this year because they will not be burdened by the need to finish leftover budget measures from the previous Republican regime. Still, losing the spending showdown with Bush in December limits their leverage in 2008.

In order to build on their majority, Democrats must combat GOP claims that this is a do-nothing Congress. They are expected to discuss that at an upcoming retreat, as well as fine-tune what their 2008 agenda will be.

It is unlikely that the tensions between House and Senate Democrats, which have flared in recent months, will continue to mount. A cohesive message in 2008, as in all election years, is vital to winning in November.

Republicans in Washington privately acknowledge that Democrats are likely to control both houses of Congress next year. But the dismally low approval ratings for Congress have gotten the attention of Democratic leaders, who know they must produce in 2008.

If things go right for Democrats this year, they will be talking about bold ideas in 2009 with a Democrat in the White House and at least a handful of new Democratic senators. But there are many hurdles for them to clear to get to that point.
