I’m less enthusiastic about the first section of the paper, on Mexico and the border. Its antagonism toward Mexico is not constructive – Mexico is indeed obstructionist in many areas, but it has been induced to be helpful in others (for instance, by interdicting many of the Central American illegals headed north). Our approach to our neighbor to the south must be firm, but not ham-handed.
On the other hand, the paper makes Trump’s earlier comments about making Mexico pay for the construction of a border wall seem less absurd. It proposes a number of ways to extract funds, including “impound all remittance payments derived from illegal wages” and increased visa fees on various Mexican travelers. These may or may not be good ideas, but they’re not preposterous.
So, while I think Ann Coulter exaggerates just a little when she calls Trump’s paper “The greatest political document since the Magna Carta,” it does clearly advance the immigration debate.
