No.
Obama has done everything he possibly can to increase the flow of people across the border.
Obama is secondary to the issue. We send billions in foreign aid to Mexico and countries in Central and South America and it has only the effect of proving the adage “Foreign aid is the taking of money from poor people in rich countries and giving it to rich people in poor countries.’’ The corrupt elites of these countries use their poor as a kind of human export capital to send back remittances in the billions out of our economy to theirs. Mexico is the richest country in Latin America, per capita it has more billionaires living in it than any Western nation. What Mexico is not , as most of the rest of Latin America isn’t as well, is a country and a society based on the respect of and the rule of law.
