I&#x27;m not defending Trump, but that&#x27;s a reach.<p>The drop started with the economic downturn in &#x27;08 -- long before Trump&#x27;s anti-immigration tirades.<p>An equally silly reading of the data is that Mexicans wanted to live in the US because Bush was president, but they hate Obama so they stopped coming and started leaving.<p>All signs point to this being economically driven.
