In a major victory for diplomacy, peace, and U.S. President Barack Obama, Senate Democrats blocked an attempt to derail the nuclear agreement between Iran, the United States, and five other world powers.

In a vote of 58-42, the Democratic and independent senators backing the deal stopped Republicans from reaching the 60-vote threshold needed to advance a resolution to reject the six-nation nuclear accord.

The development ensures that the landmark nuclear deal—which would lift economic sanctions against Iran in exchange for Tehran agreeing to limits on its domestic nuclear program for at least a decade—will take effect without a veto showdown between Congress and the White House.

And as The Hill noted, it marks “a major political victory” for Obama, who “personally lobbied Democrats to support the deal, arguing it offered the best chance to prevent Iran from obtaining a nuclear weapon over the next decade.”  

As CNN reported Thursday afternoon, “While Senate Republicans are considering a revote on the measure next week to put additional pressure on Democrats, and the House has also planned several votes against the deal, sufficient congressional support has been secured for its implementation.”
