I can download statewide NY senate districts using ...

https://tigerweb.geo.census.gov/arcgis/rest/services/TIGERweb/tigerWMS_Current/MapServer/56/query?where=STATE+%3D+36&text=&objectIds=&time=&geometry=&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentsOnly=false&datumTransformation=&parameterValues=&rangeValues=&f=geojson

When I query lat/lng against the api... I get zero results.

https://tigerweb.geo.census.gov/arcgis/rest/services/TIGERweb/tigerWMS_Current/MapServer/56/query?where=STATE+%3D+36&text=&objectIds=&time=&geometry=-73.831676%2C42.768687&geometryType=esriGeometryPoint&inSR=&spatialRel=esriSpatialRelIntersects&relationParam=&outFields=*&returnGeometry=true&returnTrueCurves=false&maxAllowableOffset=&geometryPrecision=&outSR=&returnIdsOnly=false&returnCountOnly=false&orderByFields=&groupByFieldsForStatistics=&outStatistics=&returnZ=false&returnM=false&gdbVersion=&returnDistinctValues=false&resultOffset=&resultRecordCount=&queryByDistance=&returnExtentsOnly=false&datumTransformation=&parameterValues=&rangeValues=&f=geojson

But when I map the statewide dataset and map the lat/lng I can see I should have an intersect. Can someone tell me why this intersect returns no results when the point falls within zone on the map???enter image description here

The spatial reference of the service you are querying is different from the one one of your point (EPSG 3857 vs EPSG 4326). You are trying to specify a geographic point in a projected coordinate system and therefore you get no intersection. However, you can specify the spatial reference of your point in the query with the inSR parameter. If you specify inSR=4326 in the query url you will get a result. Check the fourth line of the following url versus the fourth line of your query. inSR is empty in yours.
