Opponents of the Iran nuclear deal have all but accepted they cannot block the accord, as a growing number of congressional Democrats signal they'll supply the votes to sustain President Barack Obama's veto of a planned resolution of disapproval.
The question now is whether the resolution will even make it to Obama's desk. While passage by the Republican-controlled House is certain, Democrats in the Senate are planning to stop a resolution by using the filibuster to require a 60-vote super-majority to send it to the president. Republicans have 54 members in the Senate. Just two Senate Democrats have declared against the deal—New York's Chuck Schumer and New Jersey's Bob Menendez.
