Senator John McCain (R-AZ) no longer opposes the Comprehensive Test Ban Treaty (CTBT). McCain did not commit to voting in favor of CTBT but if he does, the U.S. will be one vote closer to finally becoming party to the CTBT. McCain influences the Republican Party significantly. If McCain supports CTBT, it will likely convince the six additional Republicans necessary to vote in favor of CTBT (Read more here). It takes 67 votes in the Senate for an international treaty to be approved by the United States.
