We’ll ignore the fact that they wouldn’t save money because they would lose their Federal transportation funding if they only offered the test in English. We won’t ignore that it’s racist; it’s barely-coded anti-immigrant rhetoric, and in the current political climate, anti-immigrant rhetoric is barely-coded anti-Latino rhetoric. And “If you want to live here, learn [English]” adds another layer: the implication that immigrants and minorities are lazy. Learning a new language and adjusting to a new culture are not easy things, and needing a driver’s license before needing English fluency is practicality, not laziness.
[UPDATE: The election is going to a runoff, probably after a recount.]
