Which party do you identify with, and which party does your House incumbent belong to?

Respondent party and House incumbent party · Asked in 20 waves, 1970–2016 · 30,374 responses · weighted estimates computed from individual responses

Dropped as not asked: 9 'R does not have major party partisanship or NA if has major party partisanship; no incumbent running; Washington D.C.; California (1974 only: due to redistricting type of race could not be determined); incumbent is not member of major party (1994,2000)'. Codebook notes: GENERAL NOTE: This variable has been created from R’s party ID (VCF0301) and from type of congressional race (VCF0902). The respondent has been considered a partisan if R was coded as ‘strong’ ‘weak’ or leaning. WARNING: In years prior to 1978, no ‘type of race’ var was present in study datasets. Data were added, however, to ‘type of race’ cumulative file var 902 for 1970, 1974 and 1976 using a lengthy case-by-case procedure. Although the resultant ‘type of race’ data have been checked to some extent, the possibility of some error must be recognized: the ‘type of race’ established for 1970, 1974 and 1976– and, as a further result, data in VCF1004 and VCF1005 for 1970, 1974 and 1976 (which have been built using type-of-race data)– should be used with caution and at the user’s risk. 2016 NOTE: Built from VCF0902 and CF0301.
