Citing “overwhelming demand,” rock and roll musician Kid Rock recently started selling Donald Trump-themed apparel. One of three T-shirts tied to the president-elect depicts a post-election map with Republican states labeled “United States of America” and Democratic states labeled “Dumbf—istan.” Another features the words “God, Guns & Trump.” The third includes an image of Trump along with a crude message directed at his opponents. The hat, which is a spinoff of Trump’s signature “Make America Great Again” cap, reads “Make America Badass Again.” The items are available through Kid Rock’s online store. (Warning: Some items feature vulgar language.) Related VideoBoone...
