WASHINGTON — The US Senate yesterday began a “vote-a-rama” to work through a massive stack of spending amendments, as the Democrat-run chamber inched closer to passing its first budget in four years.

The Senate budget has no chance of passing the GOP-run House. It nevertheless documents the Democrats’ plan to raise about $1 trillion in new tax revenue, reap $875 billion from cuts or savings, and spend $100 billion more on infrastructure and job-training programs.

Before it passes, the Senate must work through dozens of amendments. Most will fail. Some are designed just to score political points.

They’ve included a repeal of ObamaCare and the adoption of the House GOP budget. Both failed.
