Hillary Clinton has seen her edge over Donald Trump in the polls grow slightly heading into the highly anticipated first presidential debate.
According to the Real Clear Politics average, the former secretary of state leads 46.2 percent to Trump's 43.7 percent nationally. The billionaire business man has cut into Clinton's lead dramatically over the past few weeks, halving her lead from 6 points to now under 3 points.
Trump recently reached his highest chance of winning the 2016 election, according to FiveThirtyEight's Nate Silver. Silver's "Polls-plus" projection gave the GOP nominee a 44.5 percent chance of winning the presidency last week, the highest chance of victory he's seen during the entire 2016 campaign. As it stands now, Clinton has a 58.1 percent chance of victory, while Trump has dipped to 41.9 percent.
