...you are technically correct, but the dems cannot (politically speaking) toss the first female of color vice president under the bus without angering their new controllers and The Squad and a huge number of their sub divided democrats. It would be divisive and their so called majority is not large enough to carry the day in a national election and in many cases local elections. I think they will have to buy her out of the office.
...as for biden completing his current term? He would be gone already it they could get rid of Kamala.
Liberals are like a "Slinky". Totally useless, but somehow ya can't help but smile when you see one tumble down a flight of stairs!
