It's a bit baffling because Trump sending American supplies to China is the kind of thoughtful gesture our America First President never makes. Also, the kind of gesture we might have lauded in Obama, being both humanitarian and preventative.
Trump can't brag about his generosity in this case because it's the kind of thing his base abhors. Imagine if Barack Obama had sent our live saving gear to China while Americans died.
Fascinating how many different ways one President can keep f#&%ing up.
