It gets even shorter if you leave off things that can wait until a postelection lame-duck session.
Atop the list is a short-term spending bill to keep the government running past the Oct. 1 start of the new budget year. Votes on the bill aren't needed until September.
After stumbling into a politically costly partial government shutdown last fall, Republicans won't let it happen again, especially with an election just around the corner. This year's measure should be no problem.
Much more difficult, however, is the second main item of must-do business: finding more money for the Highway Trust Fund to keep road and bridge construction projects afloat. The fund is running critically low on cash. The administration says that could mean a slowdown in construction projects this summer and fall when lawmakers are back home asking voters to return them to Washington for another term. The current highway bill expires at the end of September.
"The number of (must-do) items is small," said GOP lobbyist Hazen Marshall of the Nickles Group. "But the degree of difficulty, particularly for the highway bill, is very high."
Top lawmakers and the administration all say they want to pass a multiyear highway and transit funding bill. Most Capitol Hill watchers think a temporary extension of funding is far more likely. That's still complicated.
Lawmakers will have to agree on perhaps $10 billion to $15 billion in funding to cover expected trust fund shortfalls. Optimally, Congress would act before its August vacation.
Passing those two bills is probably all that has to happen before Election Day. Congress has taken care of must-do legislation to increase the debt limit and fix Medicare's flawed payment formula.
So what will Congress do for the next few months? Not much.
There will be efforts to get the troubled appropriations process back on track in the aftermath of last year's shutdown and modest follow-up budget bargain.
Senate Majority Leader Harry Reid, D-Nev., has promised the head of the Senate Appropriations Committee, Sen. Barbara Mikulski, D-Md., a few weeks of floor time after last year's failure to pass a single appropriations bill through the Senate.
The House will try to pass as many bills of the 12 spending bills as it can, but measures funding implementation of the Affordable Care Act, the Internal Revenue Service and the Environmental Protection Agency are candidates to bog down.
In the Senate, Democrats scrambling to retain control of the chamber will stage votes to raise the minimum wage and help the middle class with rising costs for college and child care. Those are issues designed to appeal to voters in the midterm election.
