Just FYI - 2004 was 45D, 29R, 26D
There was no exit poll in 2002.
In 2000, it was 45D-28R-27I. (Sen race; Hillary Clinton beat Lazio.)
In 1998, it was 41D-34R-25I. (Gov race; Pataki won re-election in a landslide. )
In 1996, it was 42D-29R-28I. (Pres race; Clinton won Reelection.)
In 1994, it was 39D-32R-29I. (Gov race;Pataki squeaked by Cuomo.)
In 1992, it was 42D-32R-26I (Presidential Race)/ 43D-32R-25I (Senate Race; D'Amato won reelection.)
Shifts happen. The mid-term electorate is usually less Democratic and more Repubican than the Presidential year electorate. Republicans ending up in the 30s in NY mid-term elections isn't unheard of.
