I think that the topic title for this thread is meant to be a little sarcastic. It stems from some on the right, often on Fox News, who will always cast absolutely anything that happens in the world, as somehow bad for President Biden.
Record low unemployment is bad for Biden.
Inflation coming down is bad for Joe Biden.
Ending the pandemic state of emergency, which the right opposed in the first place, is bad for Joe Biden.
The case of fentanyl interdiction is a perfect example. About the time President Biden was elected, the amount of fentanyl confiscated more or less tripled and has stayed at that increased level ever since. To those who don't like Joe Biden, this is a sign of "his" border crisis. To most sane people, increased seizure of the drug would be a good thing, but not to the Biden-haters.
I think that the right assumes that the only reason that more drugs are being seized is that more drugs are coming through. That WOULD be a bad thing, but no one has proffered any evidence that this is the case. It might be true, but I would like to see evidence of that. On the other hand, it may mean that the border patrol is doing a better job of catching the stuff, which is a good thing.
And, as someone else pointed out, drugs that are seized do not have a chance to kill anyone. That's a good thing for everyone, including Joe Biden.
