Having suffered not one but several humiliating defeats on Tuesday, Republicans are in danger of embracing “comprehensive” immigration reform—which is to say, amnesty—out of panic. The GOP does need to do better among Hispanics and other voters, but this is not the way to achieve that—and, more important, it is bad policy. A formal policy of refusing to enforce the law is not obviously the best substitute for an informal policy of refusing to enforce the law.

But first, credit should be given where it is due: The Obama administration, by keeping economic growth at anemic levels, has managed to control illegal immigration better than most of its predecessors. The Reagan-era Immigration Reform and Control Act conferred amnesty upon some 3 million illegals in exchange for promises of stepped-up enforcement at the border and in the back office, but the sanctions never quite materialized. Even though some improved security measures were implemented after 9/11, the Bush years saw a 40 percent increase in the population of illegals, according to the Migration Policy Institute.

Our immigration system is in need of deep reform, but amnesty is not the first item on intelligent reformers’ to-do list, if indeed it belongs on the list at all.

We know from historical experience that immigration amnesties serve only to encourage yet more illegal immigration, and the suffering and disorder that go along with it. Illegal immigrants constitute a permanent underclass, the growth of which is in the long-term interest of neither the citizens of the United States nor of those immigrants who aspire to citizenship. Stopgap measures such as “temporary guest worker” programs simply convert that underclass from de facto to de jure.

There are many steps we can and should take toward improving our national immigration regime. It should be easier for those with job offers—particularly highly skilled, English-speaking professionals—to gain long-term residency in the United States and to embark on a path to citizenship if they so choose. And for those who are here illegally, especially those who were brought here as young children, our policy options are not restricted to amnesty or round-ups and mass deportations. {snip} Until the borders are physically secured, our most effective and most humane option is steady, consistent, judicious workplace enforcement. We do not lack the national means to enforce the law, only the political will to do so.

Republicans who believe that amnesty would buy them an electoral advantage with Hispanics are deluding themselves. That Hispanics are a natural Republican constituency because of their Catholic and family-oriented traditions is wishful thinking. Hispanics are not uniformly in favor of amnesty for illegals—polls have shown that a segment of the Hispanic population ranging from a large minority to a small majority oppose the policy. Polls also show that a substantial majority of Hispanics support Obamacare, and that Hispanics voted accordingly on Tuesday. Those who see in Hispanics a potential bloc of socially conservative voters should consider that polls consistently find blacks to be slightly more anti-abortion than whites, but they are not exactly lining up behind Rick Santorum. There is very little reason to believe that Hispanic Catholics are any more likely to vote like social conservatives than non-Hispanic Catholics. For that matter, the majority of Hispanic evangelicals voted for Obama in 2008.

The amnesty signed into law by the charismatic and popular President Reagan did not bring Hispanic voters into the Republican party; Republican congressional leaders who believe that sending one to President Obama would redound to their benefit are engaged in a defective political calculus. Nor are Hispanics the only group of voters to consider. Blue-collar whites do not appear to have turned out for Republicans in the usual numbers last week. Support for amnesty will not bring them back. If the policy advanced the national interest, that consideration might not matter. It does when supposed political advantage is the argument for the policy.

The Republican party and the conservative movement simply are not constituted for ethnic pandering, and certainly will not out-pander the party of amnesty and affirmative action. Republicans’ challenge is to convince Hispanics, blacks, women, gays, etc., that the policies of the Obama administration are inimical to their interests as Americans, not as members of any collegium of grievance.
