Critique Trump's policies and plans related to the Mexican border and deporting Mexican laborers.
But - Trump HAS no policy, unless you consider the impossible building of a Southern border wall which the government of Mexico will pay for (in his dreams!) and deporting 11 million Mexican laborers, which would take 10 years and several trillion dollars, and destroy our international reputation while wrecking our economy.  That's not a policy, that's nothing but bull pucky for the ignorant masses.
