New York has become the latest state to join an agreement that would transform the U.S. presidential election. Under the compact for a National Popular Vote, states across the country have pledged to award their electoral votes to the presidential candidate who wins the popular vote. If enough states sign on, it would guarantee the presidency goes to the candidate with the most votes nationwide. This would prevent scenarios like what happened in 2000, when Al Gore won the popular vote but still lost the election to George W. Bush. The compact will kick in only when enough states have signed on to reach a threshold of 270 electoral votes. By adding its 29 electoral votes, New York joins those already pledged by nine other states and Washington, D.C.
