Sen. Ron Johnson (R-Wis.) joined the growing chorus of GOP critics of Colorado’s ruling disqualifying former President Trump from the state’s primary ballot, arguing “radical leftism” has “infiltrated” every institution in the U.S. Asked on Fox News’s “Sunday Morning Futures” with Maria Bartiromo for his view on the Colorado ruling, Johnson said, “Well, radical leftism has infiltrated every institution in this country, our courts, our education system, government agencies. It’s a real problem.”
