Social Identity Theory suggests that individuals are motivated to support/oppose policies and politicians that benefit/harm members of their ingroup as a means of protecting their social status. Since the Republican Party’s rhetoric against immigrants in recent decades has often been viewed as an assault upon those of Latinx descent, it is not surprising that strong majorities oppose restrictionist immigration policies and support the Democratic Party. However, the existing literature has overlooked why a sizeable minority of Latinx voters express support for restrictionist immigration policies and the politicians who espouse them. Our analysis of Latinx voters with the 2012 and 2016 American National Election Studies (ANES) demonstrates that the degree to which individuals prioritize their US American identity over their Latinx identity has a significant influence over support for conservative immigration policies and GOP candidates. This relationship emerges above and beyond partisanship, ideology, and other key explanatory factors. Such attitudes likely represent an individual social mobility strategy in which members of a social group attempt to “pass” as a member of a higher-status group. Prioritizing a US American identity, supporting the Republican Party, and expressing hostility toward the interests of undocumented immigrants are a means of distinguishing themselves from a social group that has become increasingly associated with negative stereotypes. In contrast, those who are unwilling or unable to make this transition are likely pursuing a collective social mobility strategy (e.g., linked fate) whereby they attempt to enhance their individual status by elevating that of the entire social group.

身份优先级的作用：为什么一些拉丁人支持限制性主义者的移民政策和候选人

社会认同理论表明，个人有动机支持/反对有益于/伤害其群体成员的政策和政客，以此作为保护其社会地位的一种手段。由于近几十年来共和党对移民的言论经常被视为对拉丁裔的攻击，因此，多数人反对限制主义移民政策并支持民主党也就不足为奇了。但是，现有文献忽略了为什么少数拉丁裔选民表达了对限制主义移民政策以及支持这些政策的政客的支持的原因。我们通过2012年和2016年美国全国选举研究（ANES）对拉丁裔选民的分析表明，个人在优先考虑其美国裔美国人身份而不是其拉丁裔身份的程度上，对支持保守移民政策和共和党候选人的影响很大。这种关系超越了党派，意识形态和其他关键解释因素的影响。这种态度可能代表了一种个体的社会流动策略，其中社会群体的成员试图以“地位更高”的成员的身份“通过”。优先考虑美利坚合众国的身份，支持共和党以及对无证移民的利益表示敌意，这是一种使自己与日益与消极定型观念联系在一起的社会群体区别开来的手段。相比之下，
