Do tou think they fabricated the poll?
Well, put it this way: If this was really such a popular idea, why would Congress have any issues about first passing a border-security bill? Then they could go ahead with guest workers, and still have popular support for it, right? But they won't do that, precisely because they know that once the border is secured, there won't be the same appetite for guest workers.
"Do tou think they fabricated the poll?"
Yes, I do when every other poll taken over the last few years shows an overwhelming opposition to this. There is a collection of the polling data at fairusa if you don't believe me.
