Other than his commitment to DACA, this op-ed is the standard GOP position on immigration: stronger borders with a pathway to citizenship for non-criminal aliens.
Like a typical Republican, Dubya avoids any mention of requiring employers to use E-Verify, thus ensuring that businesses can continue hiring illegal workers with zero consequence. This actually used to be a hill that pro-labor and conservative Democrats would die on in the 1990s-2000s.
The politics around immigration in this country continue to get more and more abstract. Democrats have succeeded in making it into a racial "culture war" issue instead of talking about its basic national security or economic considerations.
You got to admit that what animates most Republicans on the subject of immigration continues to be the racial demographics of said immigrants.
If they cared about national security then many Republican leaders will be for beefing up cybersecurity against actual threats likes Russia and China or come out strongly to condemn white nationalist groups who make up the largest threat to American national security. If they cared about economic issues then they will support a minimum wage increase, affordable college so people can rise in socioeconomic status, and training in emerging markets for those who can not.
Instead, Republican leaders ignore all of those things and instead double down on the same racist tropes that immigrants are bringing crime and pose a threat against the native culture. It is why some fringe conspiracies theory like the "Replacement Theory" is even known among a broader public and why people like GWB find themselves left of the current right-wing movement.
