Suffolk county, Eastern Long Island went for Trump in 2016.
Unfortunately neighboring Nassau County ( closer to NYC ) went for Hillary in 2016 ... barely. Hopefully Nassau changes her mind this year.
Long Island has been hit by a string of MS-13 gang related shootings and killings prior to 2016 ( because Obama housed a lot of Central American young illegals in the once peaceful suburbs of Suffolk County ).
Trump and Pence went to Long Island and sent Federal help for local police to clean the entire place up.
Yes, Suffolk County and Staten Island went for Trump in 2016. I think there is an excellent chance of pulling Nassau County into the Trump column this time around as well.
