Popular vote share
We've collected three polls for the New York 25th. We’re adjusting poll results in three ways: Polls of registered voters or all adults are adjusted to a likely-voter basis; older polls are adjusted based on shifts in the generic congressional ballot since the poll was conducted; and polls are adjusted for house effects (the tendency for a firm’s polls to lean toward Democrats or Republicans). Polls with larger sample sizes and those conducted by higher-quality polling agencies are given more weight, as are more recent polls.
|margin||likely voter||Time-line||House effects||Adjusted margin|
A = adults
RV = Registered voters
V = voters
LV = likely voters
= partisan poll
Our latest coverage
#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 Classic and Deluxe versions of our model use several non-polling factors to forecast the vote share margin in each district.
|NY-25 is 15.0 percentage points more Democratic-leaning than the country overall, based on how it has voted in recent presidential and state legislative elections. It voted for Clinton in 2016 and Obama in 2012.|
|Previous incumbent's margin in last election|
|A Democrat won by 12.4 percentage points in this district in 2016. Previous district results are not strongly predictive in races without incumbents.|
|Democrats lead by an average of 8.6 percentage points in polls of the generic congressional ballot.|
|As of Oct. 17, Joseph Morelle had raised $893,000 in individual contributions (67% of all such contributions to the major-party candidates); Jim Maxwell had raised $434,000 (33%).|
|Morelle has held elected office before but Maxwell hasn't.|
|Neither candidate is involved in a scandal.|
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||D+22.3||D+22.9|
|Sabato's Crystal Ball||D+22.3||D+21.9|
