The top issue during the Iowa caucus was immigration. "60 Minutes" just ran a segment on illegal aliens using TikTok for a step-by-step guide on where and how to enter the country illegally. Texas Gov. Greg Abbott deployed his state's National Guard to defend its border. Several migrants beat up NYPD cops. Homeland Security Secretary Alejandro Mayorkas, who once brazenly said, "our borders are not open," barely dodged impeachment. And now, even Sharpton calls the unprecedented number of illegal entries an "invasion."
