Merely in your uninformed opinion."Nativist Hatred of immigrants" is a fact of life in America since the Europeans came to the New World. Anyone who denies knows nothing of the American narrative.
There are real and valid reasons to be against the current high level of immigration and calling someone a "nativist" is nothing but a cowardly intellectually dishonest dodge to avoid defending a policy based on it's merits.
And John McCain did not run a racist campaign and the lying libs in the media who said he did were lying scum and will do the same to any republicans, "far right" or moderate as hell.
So, are you claiming that
a. The US has unlimited capacity to absorb unlimited numbers of under educated, low skilled immigrants?
or
b. That John McCain ran a racist campaign?
It wasn't clear to me which of my points you were disagreeing with.
