Ten hawkish Democratic senators vowed Jan. 27 to vote against Iran sanctions legislation if it comes up before the end of March, robbing Republicans of the votes they need to override a veto.
The announcement is a clear win for President Barack Obama, who has repeatedly warned lawmakers that targeting Iran now could blow up delicate diplomatic talks. The latest development all but assures that the Senate leadership will delay a vote rather than turn Iran into a partisan issue, with even top Republicans making that case.
