Nate Silver: Dems Likely to Win the House, but Anything Can Happen

'The range of outcomes in the House is really wide. Our range, which covers 80 percent of outcomes goes from, on the low end, about 15 Democratic pickups, all the way to low to mid 50s, 52 or 53'

Pollster Nate Silver told ABC’s “This Week” the Democrats have a strong chance of winning the U.S. House of Representatives, but made clear that anything can happen.

"So in the House we have Democrats with about a 4 in 5 chance of winning," Silver, who runs the website FiveThirtyEight, said Sunday morning, adding however that the "polls aren't always right."

"The range of outcomes in the House is really wide. Our range, which covers 80 percent of outcomes goes from, on the low end, about 15 Democratic pickups, all the way to low to mid 50s, 52 or 53."

"Most of those are under 23, which is how many seats they would need to win to take the House," he said."

"But no one should be surprised if they only win 19 seats and no one should be surprised if they win 51 seats," Silver added. "Those are both extremely possible, based on how accurate polls are in the real world."
