EnglishPete? Naso? Sanchez? Thomas Jackson? Defend this because I'd love to see how such blatant goddamn ignorance can be spun in a positive light.
I will, actually. I've mixed up Medicare and Medicaid more than once, they're just one phoneme apart from each other. There are many examples of T***p's incompetence but that's a pretty weak one.
You also weren't born in America, and you're not the President of the United States. 
Plus mixing up the two words is quite different from not knowing what the two things are.
What makes this even sadder is that Trump is old. Shouldn't he know a thing or two about Medicare?
