changes in 1978 data for type of House race (SEE VCF0902).  1984
corrections to original type of race data (SEE VCF0902) are not
reflected in VCF0903-905.
Code 1 includes congressional districts where 2 incumbents ran due to 
redistricting.
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 2.
2004 NOTE:
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 2; when unclear whether
either incumbent had previously represented the district then
2 has been coded.
