GENERAL NOTE:
This variable is available for 1970 and 1974-1992.  The 1970, 1974 and
1976 data were derived from VCF0902 (Q.V.).
Note that for districts where 2 incumbents were running due to
redistricting, neither of whom had previously represented R's location,
this variable has been coded 0.
1978 NOTE:
Several changes to data for type of House race from 1978 have been
made since previous release of the Cumulative Data File (see notes
VCF0902). As a result, VCF0904 and VCF0905 have been changed
accordingly.  
1984 NOTE:
Corrections to original type of race data (SEE VCF0902) are not 
reflected in VCF0903-905.
2002 NOTE:
Several cases a where non-major-party incumbent was opposed by a major 
party challenger have been coded 2.
