Do the math, and that leaves out Amy Klobuchar, Tulsi Gabbard, Tom Steyer and of course ... the former Vice President and one of the favorites to land the nomination, Biden.
The snub's not a big surprise, though ... Joe had a pretty rough night. He came out on the losing end of a couple big moments, including a pot shot from Booker about Biden's resistance to the legalization of marijuana.
MLK's son touched on that subject as well, mostly echoing Booker's message ... but did concede that Biden's insistence on doing more research on the subject isn't necessarily a bad thing.
Speaking of bad things -- Joe had another snafu while addressing violence against women by making a very poor choice of words ... and failing to recognize his mistake.
So, maybe King III was being nice by not mentioning Biden at all.
