History. 0 of 6: in no year when the Senate never agreed a House plan with orders for a reconciliation bill did the House pass such a bill in the session between the election and the end of that Congress. The only bill, in 2012, passed in May, 42 days after the House plan. With the 16 plans the Senate agreed, the House passed a bill in 17 of 22, all of them before the election.

We looked for cases where the US House passed a budget plan that opened the way to a reconciliation bill, with no more than five votes from the other party, and the Senate never agreed to such a plan for that year. We found six such years since 1990: 1998, 2004, 2006, 2008, 2012 and 2013. (Congressional Research Service; Congressional Research Service)
