Art Sisneros, one of 538 electors with the final say on who becomes the next U.S. president, says he's undecided on how to vote. The 40-year-old family man from Dayton is among the 38 people chosen to represent Texas in the Electoral College. That group will gather Dec. 19 in 50 state capitols around the country to vote on who wins the election. If all electors cast their votes in keeping with the winner of each state, then Donald Trump wins, even though Hillary Clinton received more popular votes overall.
