How is anti-illegal immigration messaging affecting Republican Party support and border security efforts?

According to Yuma County Supervisor Jonathan Lines, anti-illegal immigration messaging has driven a significant surge in Republican Party registrations, with 100% community support for this approach. He emphasizes that this message needs to be delivered directly to people in foreign countries to combat cartel recruitment and trafficking operations. Lines notes that cartels continue to recruit mules to transport narcotics across the border, but are experiencing reduced success in human trafficking due to the administration's stronger enforcement. This messaging strategy appears to be effectively supporting border security efforts while simultaneously building political support for the Republican Party.
