Americans are now split on who they think will win the 2016 presidential election—signaling that many now think that Donald Trump has a serious chance against Hillary Clinton, the current Democratic front-runner, in the fall. In the minds of voters, Trump’s chances of winning the presidential race have improved, with 47 percent saying they think Clinton will win the general election contest and 46 percent thinking Trump will win. This is a significant change from last week, when a majority of voters put their odds on Clinton over Trump (51 percent to 42 percent).
