Simply rejecting immigration reforms aimed at a path to citizenship carry big political risks as well, including the possibility of reducing Republicans’ already-weak standing with the Hispanic voters (and future voters).
The takeaway? Hispanic citizens’ lower turnout and registration rates have so far limited their political impact. But if the significant share of Hispanic non-citizens gain a path to citizenship and actually start voting, the electoral map could change much more quickly than what the slowing changing demographics of the country suggest. And that would be a bad thing for Republicans.
