As Senate nears $1 trillion infrastructure vote, deficit takes a back seat

“That will be an extraordinary debate of enormous dimension,” Senator Mitch McConnell of Kentucky, the Republican leader, predicted. “I can’t think of a single issue that underscores the difference between the two parties more than the reckless tax-and-spending spree that we’ll be dealing with here in the next week or two.”

In the past, the Congressional Budget Office has loomed like the sword of Damocles over delicate legislative compromises, a nonpartisan scorekeeper whose rulings on the nation’s finances and fortunes could sink or propel hard-fought policy measures. The budget office’s prediction that successive Republican measures to replace the Affordable Care Act would cost tens of millions of Americans their health insurance effectively doomed those efforts.

But the 10-year price tag the budget office put out this week for the bipartisan infrastructure bill changed no minds, even though it reported that the measure would tack a quarter trillion dollars to an already swollen sea of federal red ink. Many Republicans are beginning to regard spending on highways, bridges, rail lines and broadband the way Democrats have for years — as a long-term investment in the nation’s economic future that need not cause short-term deficit heartburn, especially when borrowing costs are at rock-bottom rates.
