Senate Democrats promise to pass a budget. Why is this a big deal?

Sen. Chuck Schumer (D-N.Y.) made headlines Sunday morning by promising that Senate Democrats will write and pass a full tax and spending bill by the March 1 deadline for the next budget. "It's going to be a great opportunity for us because in our budget that we will pass, we will have tax reform, which many of my Republican colleagues like. But it's going to include revenues," Schumer said on "Meet The Press."
