Just like they predicted Trump's chance of winning the primary as 2%.

Hilarious defence of their work in recent tweet

"Clinton came within 2 points of 307 electoral votes, in which case polls would have been right in 49 of 50 states. "

ie. If the results had been different, our prediction would have been correct.

First, that comment is about the polls, not their model.

Second, it's called a polling error. It's actually a thing.

This election happened to be extremely sensitive to polling errors due to the nature of the electoral college and the fact that a number of key races were extremely tight.

When an average poll has a 3% margin of error, and you factor in state-level correlations (and the fact that the state level polls tend to have more variable quality than national polls), a slight error results in a huge swing.

Which is the entire point they're making, if you're willing to set aside the snark and read what they wrote (since it's actually, you know, interesting and informative).

Sounds like you didn't read the part where they reviewed their research and looked at where they went wrong.
