No matter how persuasive President Trump is, it’s unlikely he can round up enough Democrats to get 60 votes in the Senate for tax reform. That means Republicans will need to use the Senate’s reconciliation process, which avoids the filibuster, to pass their plan with 51 votes. But first the House and Senate must pass a budget resolution—and soon.
A budget resolution sets spending levels and authorizes congressional committees to prepare bills fulfilling the blueprint. With the reconciliation plan in mind, this year’s resolution would set the size of the tax reform and then instruct the House Ways and Means Committee and the Senate Finance Committee to flesh out the provisions.
Gaining agreement on a budget resolution is always tough. No more than a handful of lawmakers from the opposition party ever vote for the majority’s resolution. It helps that Republicans control both the House and Senate, but the GOP must still resolve its internal philosophical disagreements.
House Republicans tend to insist on resolutions that balance the budget within 10 years. This means resolutions that pledge to slow substantially the growth of entitlement spending. Such promises are rarely fulfilled. But putting them in the budget blueprint fuels Democratic ads claiming Republicans will throw grandma off the cliff and deprive poor children of free school lunches. Knowing this, Senate Republicans tend to want resolutions that reach balance after 10 years. Another GOP tension is between defense hawks, who want increased military spending, and deficit hawks, who want all spending restrained or cut.
