While the Democratic presidential nominee has a 65.7 percent chance of winning the presidency on Tuesday, she is not "in a terribly safe position," the pollster said on ABC's "This Week." 

"The electoral map is actually less solid for Clinton than it was for Obama four years ago," Silver said. 

Silver came to notoriety by correctly predicting President Obama's victories in 2008 and 2012. 

Clinton is weaker among Midwestern voters, while Obama had leads in states like Ohio. 

In FiveThirtyEight's election forecast, Clinton has the 270 electoral votes needed to clinch the White House. 

"Clinton has about 270, so she's one state away from losing the Electoral College," he said.
