Article after article covering the prominence of immigration and border security in the Republican campaigns for U.S. Senate and president in Texas have rightly noted the long-established salience of immigration and the border to Republican voters, and the central role of these issues in the “closing arguments” of GOP candidates at the top of the ballot in Texas, Donald Trump and Ted Cruz.
But clear as this pattern is, it doesn’t explain why the issue maintains salience in the face of clear policy changes by the Biden administration, or the subsequent near-term decline in migrant traffic at the U.S.-Mexico border from historic highs in the last 11 months to the fewest encounters in the last four years. It can easily be made to seem like a puzzle: if the problem has been addressed and has abated, why is it still so important to Republican voters?
