# What goes into the
icon_classic_2
classic forecast in the Illinois 16th

The Classic version of our model projects a race’s outcome by taking a weighted average of polls of a district (if available), polls of similar districts (CANTOR) and non-polling factors (fundamentals). It is then reverted toward a mean based on long-term trends in midterms and presidential approval ratings.

#Similar districts and CANTOR

Our district similarity scores are based on demographic, geographic and political characteristics; if two districts have a score of 100, it means they are perfectly identical. These scores inform a system we use — CANTOR, or Congressional Algorithm using Neighboring Typologies to Optimize Regression — to infer what polling would say in unpolled or lightly polled districts, given what it says in similar districts.

#The “fundamentals”

The Classic and Deluxe versions of our model use several non-polling factors to forecast the vote share margin in each district.

FactorImpactExplanation
Incumbency
2.9
Adam Kinzinger has been elected to 4 terms. Congress has only an 18.0% approval rating, reducing the incumbency advantage.

IL-16 is 18.0 percentage points more Republican-leaning than the country overall, based on how it has voted in recent presidential and state legislative elections. It voted for Trump in 2016 and Romney in 2012.
Incumbent's margin in last election
13.1
Kinzinger won by 99.9 percentage points in 2016, but did not face major-party opposition.
Generic ballot
6.7
Democrats lead by an average of 8.3 percentage points in polls of the generic congressional ballot.
Fundraising
2.1
As of June 30, Kinzinger had raised $353,000 in individual contributions (63% of all such contributions to the major-party candidates); Sara Dady had raised $205,000 (37%).
Incumbent's voting record in Congress
0.4
Kinzinger has voted with Republicans 79% of the time in roll-call votes in recent sessions of Congress.
Challenger experience
0.7
Dady has never held elected office.

Total
R+18.2

#Expert ratings

The Deluxe version of our model calculates an implied margin for each race based on expert race ratings from The Cook Political Report, Inside Elections and Sabato's Crystal Ball; it then adjusts that margin toward its estimate of the national political environment.
