In the Summer of Trump, curtailing illegal immigration has become a much more important issue for Republican voters and candidates alike than it was only a few months ago. Following Trump’s lead, the GOP’s 2016 field has begun to satisfy their voters’ desire for tougher immigration rhetoric and policy. This is a virtue. Donald Trump is not capable of putting any policy meat on the bare-bones bombast that has typified his candidacy, but other candidates with the requisite faculties and expertise are starting to float smart reforms to immigration law enforcement. While the arguments that contend Trump’s rise has been wholly unproductive for the GOP are compelling, his candidacy has yielded one substantial good. A welcome side effect of this renewed focus on border security has been to uncover the extent to which the left regards almost any enforcement of American immigration laws as anathema.
