I have never seen an issue where the short-term interests of Republican presidential candidates in the primaries were more starkly at odds with the long-term interests of the party itself. ~Michael Gerson

Gerson is right about one thing (and one thing only): there is a stark opposition.  There is a short-term temptation for Republican candidates this year and next to pursue Hispanic votes in the general election through the shameless and misguided pandering of embracing Gerson’s preferred, horrible immigration policy, which, if enacted, would result in the guaranteed long-term destruction of the GOP as a competitive national party.  There is a temptation to treat Hispanic voters like idiots and pretend that liberalising immigration is their top priority (only slightly less condescending than the old Republican effort in the ’90s to try to build up support among Hispanics by supporting Puerto Rican statehood).  Of course, the reason why Hispanics do not tend to vote for Republicans and young Hispanics are even less likely to do so is that these voters do not support the various other, non-immigration policies championed by the GOP.  This is, in fact, why most immigrants tend to vote for the Democrats: Democrats propose policies on social services, education, welfare and the like that are more likely to benefit immigrants, or which are more likely to be in keeping with the political traditions they have brought with them from their old countries.  Additionally, Republicans cannot outdo Democrats in their enthusiasm for multiculturalism, since they have no enthusiasm for it.  They cannot be insistent on assimilation, which is what their constituents demand, while playing up to bilingualism or rhetoric about strength in diversity.  

Hispanic voters’ opinions on immigration policy are hardly monolithic.  The idea that capitulating to immigration liberalisation or amnesty will win over these voters assumes that actual Hispanic voters want such policies, when a sizeable number of them may prefer immigration restriction.  Gerson wants the GOP to do two incredibly stupid things at the same time: pander to Hispanics by adopting strongly pro-immigration views, thus alienating core constituencies of the party, and simultaneously insult the Hispanics with this pandering while ignoring any and all other policy issues that are the actual source of Hispanic alienation from the GOP.  It is a combination of substantively bad policy with an embarrassing attempt to employ the symbolic politics that both parties use to feign concern for this or that community.  It would be much more refreshing if pro-immigration Republicans could at least acknowledge that they support liberalisation and amnesty because it suits the interests of large businesses even though it means future doom for the GOP.
