mangle-pander. Wow!
What Biden actually said was, “I come from a state that has the eighth-largest Black population in the country, and as they say the saying goes where I come, you brung me to the dance early on!“
… What Biden was trying to say in his increasingly senescent way was, “You dance with the one who brung ya.” That is, as an inexplicably long-serving Senator from Delaware, he has always relied on black voters from Pennsylvania to get him elected. Of course that doesn’t make any sense, either, but at least he would have gotten the expression correct. You know, the expression that figuratively-literally every American who ever lived has said many times without ever mangling it.
