In my native Long Island, the chance to knock Bishop out was 2010 and it didn't happen. Long Island will probably go 55% democratic in November as a whole, far different from when the island was a GOP stronghold back in the "Rockefeller GOP" days.
If anything the "Rockefeller GOP days" saw the start of the GOP decline on LI and in general:

The reason that Bishop won was because of the NY GOP establishment creating an unnecessary distraction for Altschuler by trying to insert a favored candidate into the primary instead of him. In fact, most of the GOP's missed opportunties in NY recently can be laid at the feet of the state party organization.
