Yes, absolutely. The vast majority of engineers are fairly right-leaning.

CS is very left-leaning compared to most engineering professions, so if you include CS it throws the overall numbers towards left-leaning, but I personally wouldn't consider general CS to be an engineering field. Certain subfields, certainly, but they're a minority. My uni doesn't even have it in the same department as engineering, so that my inform my opinion there.
