For the new Republican Congress, the 2016 budget is where the rubber meets the road.

The GOP has 75 days to produce a fiscal 2016 budget resolution and move it through the House and Senate — and then less than six months to dispose of the dozen appropriations bills required to fund the government after Sept. 30. It’s a tall but critical task for a potentially fractious body of Republicans that stormed Capitol Hill intent on moving the needle rightward and proving they can govern.
