– Frequently Asked Questions

How you do determine your race ratings?
Currently, our race ratings are determined by averaging the ratings of four top analysts—Decision Desk, Larry Sabato’s Crystal Ball, the Cook Political Report, and Inside Elections. As 2018 unfolds, we will add the assessments of other analysts into the mix, include other data in our formula, and add our own independent assessment.


Why do you show a range of outcomes on your Scoreboards rather than a single projection?
Early in a campaign season, fundamental factors can provide a general sense of which individual races might be in play. The partisan composition and electoral history are among the most important indicators, along with the status of the incumbent.

However, it is impossible to know what the political environment will be like on Election Day. If the environment is more favorable to Democrats, then Democrats can be expected to win most of the toss-up and other close races. The reverse is also true. Our Scoreboards are designed to reflect that uncertainty.

It is reasonable to expect, but far from certain, that the gap between the various turnout models will decrease as Election Day draws nearer.
