With only a day left before Election Day, the wild and unpredictable 2016 U.S. presidential election is about to add another distinction as the most wagered upon political event in history.

It’s a tight race between Democratic nominee Hillary and Republican Donald Trump, with many opinion polls showing Trump closing the gap following FBI’s announcement that they were reviewing the former secretary of state’s emails. On Sunday, the FBI director said the inquiry has ended and they found nothing that will change the bureau’s original conclusion, effectively lifting a dark cloud that has been hanging over Clinton’s campaign.

But with the final polls trickling in, FBI’s announcement may not have as much of an impact as some experts believe. According to a new NBC News/Wall Street Journal national poll, Clinton retains a modest national lead of 44 percent compared to Trump’s 40 percent.
