Mostly because the Republicans hammered out a pretty hefty budget deal in early 2018
On Wednesday, Senate Majority Leader Mitch McConnell and Minority Leader Chuck Schumer announced a deal on budget caps that would increase investments in domestic programs and the military by roughly $300 billion over the next two years: The deal lifts funding for domestic programs by $128 billion and hikes defense budgets by $160 billion.
Remember that the last shutdown was caused by Democrats stonewalling over DACA
The bill does not address the fate of young immigrants who were brought to the country illegally as children and have been shielded from deportation by an Obama-era program, known as Deferred Action for Childhood Arrivals, or DACA, that Mr. Trump moved last year to end.
Republicans likely did not want to reopen the DACA issue in an election year, nor did they want to irk more Conservative members of their own party by spending even more on top of the massive deficit the budget created
That additional spending comes at the expense of adding even further to the national debt, which has topped $21 trillion. The growing debt has seemed of minimal concern on Capitol Hill in recent months, where Republicans passed a sweeping tax overhaul late last year that will also result in piling up more debt.
To some frustrated lawmakers, the heft of the spending bill was the very problem.
