Seems that GOP-dominated redistricting if anything limited Dem gains.
NY-01 was actually not changed at all(maybe a tiny bit) in 2001. IN-08 was made slightly more Dem as was NC-11. MI-09 was made marginally more GOP.
You are correct about NY-1. The district changed only very slightly and the difference had virtually no impact as the changes in registration between March 02 (the last enrollment figures prior to redistricting) and November 02 in the district was almost exactly the same as the change in Suffolk County as a whole.
NY-01 GOP + 13.78 to GOP +13.39 (net change Dems +.3876)
Suffolk GOP +9.76 to GOP + 9.33 (net change Dems +.4224)
So the changes were pretty muvh as identical as it can get
FTR the advantage for the GOP in NY-01 as of 4/09 5.90 & in Suffolk as a whole it is 1.57
