The next chapter in the tumultuous U.S. presidential election plays out Monday, with voting in the Electoral College expected to officially confirm that billionaire real estate mogul Donald Trump will become the country’s 45th president. Americans have known since early November that Trump would take over the White House when he is inaugurated January 20. U.S. presidential elections, however, are not determined by the national popular vote, but rather by the individual outcomes in presidential balloting in all 50 states and the national capital city, Washington.
