Increase in illegal border crossings could help Trump

I have noted repeatedly that net immigration from Mexico to the United States has been zero or roughly that since the collapse of the housing market in 2007. But illegal movement across the U.S.-Mexico border continues and is accelerating, as a report from the Pew Research Center notes.

The number of unaccompanied children in the first half of fiscal year 2016 is below that of the previous year, but almost equal to that in fiscal year 2014, when the surge of unaccompanied children first made headlines. And the number of children coming in with families in the first half of fiscal year 2016 is 62 percent above the level of the corresponding period of fiscal year 2014.
