Nah. Nobody cares what Gingrich says. The only reason we know about it is because he’s a D-lister political celebrity and when he blathers about something it helps to fill the vast and insatiable maw of the mediasphere. He’s a ridiculous person, though, and people have had decades to see it. Nobody thinks the lieutenant governor of Pennsylvania has gang connections. And anyone who might entertain the idea wouldn’t have been voting for him anyway.
ETA I went and looked at exactly what he said, and it just can’t be more absurd. He said the tat was either from a song about heroin use or a tribute to the Crips, which is maybe one of the most ridiculous and baseless things you could dream up to say. Even as wild, nonsensical calumny it’s just stupid. You can’t say a thing is either one absurd thing or a different absurd thing when there’s no possible reason to find either plausible. I guess he stopped even trying a long time ago. Someone said years ago that if they shook him awake and said Trump had just nationalized the banks, he would say, “Isn’t it wonderful that we have such a bold, innovative thinker as president” and go back to sleep. Like I said, he’s a ridiculous person. Now, in an era in which Qanon is a thing, you have to acknowledge that people will believe some ridiculous stuff. But we’re not talking about those people. We’re talking about Fetterman voters. They won’t have any time for this.
