This YouTube posting by the "Trump Mafia" (note their bottom-right stamp) — whose Twitter page, for some diseased, entirely Trump-unrelated reason, features a partially undressed Asian woman — exhibits just how clueless many of Trump's supporters are.
This particular outfit seems to believe that this recent CNN interview of the meretricious Sean Duffy, in which host John Berman disembowels the slithering former congressman inch by inch, actually supports their vision of an ever-victorious, always invincible Trump administration.
These Trump "mafia" boys have the conspicuous IQ of a mothball, which, in their favor, is at least a couple points higher than that of the real goons.
Naturally Col. Vindman is "incredibly concerned about Ukrainian defense." That's his job, nitwit. U.S. national security rests heavily on Ukraine's defense — so Duffy, by adding that you really "don't know his [concomitant] concern about American policy," as any reasonably intelligent American would, then you should join the alarmingly low-IQ "Trump Mafia" boys in their playroom.
