Donald Trump who likes to mock Joe Biden for any mistakes he makes recently said this, “A very big hello to a place where we've done very well: Sioux Falls. Thank you very much, Sioux Falls," Trump boomed into the microphone as he launched into his remarks. Only problem is, he was in Sioux City, Iowa at the time. Sioux Falls is in South Dakota. The guy doesn’t even know what state he is in. Does he have dementia?
