It is very likely he will be the face of the new "progressive" party, heading into the 2020 political cycle.
We already know how good he is at having "imaginary" friends, such as "T-Bone", as well as making a Pampers delivery to a woman who could not leave her home because the street she lived in was snowbound, due to his failing abilities as mayor of Newark.
Here is that story quoted from an American Thinker article:
But as Byers told Politico she never needed his photo-op heroics. “The only reason he brought me Pampers was that it had been three days and our street hadn’t been plowed,” she said. “I have five kids and, trust me, I don’t just run out of Pampers. All we wanted was for him to plow our streets. It’s about knowing how to manage a city.”
Yes, he is a POS , but to testify against Sessions and refer to him as an individual who holds "racist views" makes Booker a much worse POS
