# What goes into the

classic forecast in the Texas 19th

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.

Factor	Impact	Explanation
Incumbency	3.0	Jodey Arrington has been elected to 1 term. Congress has only a 20.1% approval rating, reducing the incumbency advantage.
District partisanship	20.2	TX-19 is 54.5 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. Texas has been considerably more Republican in state legislative elections than in presidential elections.
Incumbent's margin in last election	28.2	Arrington won by 78.1 percentage points in 2016 in an open-seat race, but did not face major-party opposition.
Generic ballot	6.5	Democrats lead by an average of 8.6 percentage points in polls of the generic congressional ballot.
Fundraising	9.5	As of Oct. 17, Arrington had raised $765,000 in individual contributions (91% of all such contributions to the major-party candidates); Miguel Levario had raised $80,000 (9%).
Incumbent's voting record in Congress	1.9	Arrington has voted with Republicans 87% of the time in roll-call votes in recent sessions of Congress. Candidates who vote with their party very frequently tend to underperform at the ballot booth, other factors held equal.
Challenger experience	0.6	Levario has never held elected office.
Scandals	0.0	Neither candidate is involved in a scandal.
Total	R+53.1

#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.

Cook Political Report	Solid R	R+53.6	R+53.0
Inside Elections	Solid R	R+53.6	R+52.7
