Calls for a recount of ballots in the American presidential electiongrew louder this week as Hillary Clinton increased her lead in the popular vote.News media say Clinton, the candidate of the Democratic Party,lost the election to businessman Donald Trump, the Republican candidate.They say he will win more electoral votes than the former Secretary of State.Trump is busy forming a new government.Political experts say a vote recount is unlikelyto keep him from being sworn-in as president on January 20th, 2017.Clinton won the popular vote– winning more than 2 million more votes than Trump,according to the Cook Political Report.But in the United States, the candidate who wins the most votesdoes not always win the presidency.If Trump wins, as appears likely, he would be the fifth personto become president after losing the popular vote.The 538-member Electoral College decides the presidential election, not the popular vote.Electoral College members are chosen state-by-state-- based on which candidates win the most votesin the 50 states and the District of Columbia.As of this week, Trump has 306 Electoral College votes,while Clinton has 232.Trump's number had been 290 until Michigan election officials announced on Fridaythat he won the state by 10,704 votes.That was the closest presidential election in Michigan's history.More than 4.7 million people there marked ballots in the November 8 vote.Last week, Clinton campaign head John Podestaspoke with lawyers and computer scientistswho urged him to ask for a recount in three states:Michigan, Pennsylvania and Wisconsin.They said it is possible that voting machines could have been attacked to affect the results.Trump's lead in the three states was 1.2 percent,according to The New York Times newspaper.If Clinton, instead of Trump, won those three states,she would end up with 274 Electoral College votes, enough to win the presidency.The experts, mentioned in a New York Magazine story,said their findings show Clinton's support dropped seven pointsin areas that used electronic voting machines.Those machines, the experts said, are more open to hacking.So far, the Clinton campaign has not reacted to calls for a vote recount.But another presidential candidate, Jill Stein,began raising money required to finance recountsin Michigan, Pennsylvania and Wisconsin.As of Friday, she had raised $5 million.That is enough, the Stein campaign said,to start recounts in all three states.Stein, the Green Party candidate,won a little more than one percent of the popular vote.A statement on her website said the recount is not meant to help Clinton,whom Stein criticized during the election.It is "about protecting our democracy," the Stein campaign said.Still, it is very unlikely her recount effortswill keep Trump from winning the presidency,according to Nate Silver, a political expert.He operates the website FiveThirtyEight.Silver told VOA it is unlikely unlawful activities affected the election results.He said the differences between districts using electronic voting machinesin Michigan, Pennsylvania and Wisconsincould be explained by race and education levels.He said they are the two factors that most closely predicted votingin the 2016 presidential election.The 538 members of the Electoral Collegeare set to officially choose the next president on December 19.Two Democratic members of the Electoral Collegecalled on members to vote their conscience,even if that means going against the wishes of votersin the states they represent.They said that Trump lacks the skills necessary to serve as president.But so far, there are no signs enough Electoral College memberswill change their votes to keep Trump from winning.Before Election Day, Clinton, who had been expected to win,promised to accept the election results.Trump, who had said he thought cheating might affect the results,refused to make such a promise."We are a country based on laws,and we've had hot, contested elections going back to the very beginning,"Clinton said, before the voting."But one of our hallmarks has always beenthat we accept the outcomes of our election."The last person to lose the popular vote but win the presidential electionwas Republican George W. Bush in 2000.He lost to Democrat Al Gore that year by 547,000 votes.
