"Properly controlled immigration can be good for America" is a meaningless question. Of course Democrats would think Republicans would be opposed to this idea.

"Properly controlled immigration can be good for America" is a meaningless question. Of course Democrats would think Republicans would be opposed to this idea. The idea of "proper control" is the whole debate! We have republicans who feel that building a wall is part of properly controlling things and democrats who think it's a moral outrage. Several of these questions are phrased so as to make them non-partisan and in doing so create a "bad people on both sides" effect. Vague statements like this create bad sociology my friends! This isn't about a perception gap. It's about not putting together very good polling questions and then drawing some conclusions based on them.
