It is unfortunate, though not surprising, that a group advocating high levels of immigration and claiming to speak for conservative principles has resorted to character attacks in an attempt to discredit the Center for Immigration Studies (CIS) and other influential organizations. In the Feb. 15 front-page article “Immigrant policy stirs new battle in the GOP,” Alfonso Aguilar of the Latino Partnership for Conservative Principles criticizes us but does not offer any actual critique of our research.

Our findings are quite consistent with those of the U.S. Commission on Immigration Reform (the Jordan Commission) that spent more than five years studying immigration and concluded that a more moderate pace of immigration would make sense for the country.

Americans of all political affiliations support better enforcement of our immigration laws. The only question is whether the GOP will follow the Democratic Party’s lead and embrace failed amnesty policies of the past or pursue a more rational policy.
