First,
Some of those voters have relatives from Mexico, and having people
campaigning on keeping your relative out tends to "sour" the vote.

Second,
Some of the anti-immigration legislation has victimized people
who were already here as citizens -- however, the loose-wording of
the law and the use of racial profiling has (again) hit voters


The point is that the voters dont exist here in a vacuum, and they see
what is happening and what is being said and how they are being caught up
in it as well...
