WASHINGTON — President Donald Trump has warned Congress that he will never sign another foot-tall, $1 trillion-plus government-wide spending bill like the one he did in March. His message to lawmakers in both parties: Get your act together before the next budget lands on my desk.

After a brief government shutdown earlier this year, Democrats and Republicans now agree on the need for budgeting day-to-day operations of government the old-fashioned way. That means weeks of open debate and amendments that empower rank-and-file lawmakers, rather than concentrating power in the hands of a few leaders meeting in secret.

But Capitol Hill’s dysfunction is so pervasive that even the most optimistic predictions are for only a handful of the 12 annual spending bills to make it into law by Oct. 1, the start of the new budget year. The rest may get bundled together into a single, massive measure yet again.

The worst-case scenario? A government shutdown just a month before Election Day, Nov. 6, as Republicans and Democrats fight for control of the House and possibly the Senate. Trump is agitating for more money for his border wall.

At stake is the funding for daily operations of government agencies. Many conservative Republicans won’t vote for some bills because they think they spend too much money.
