It's never been the role of the incumbent VP to be the person to choose the next president (I also guess Nixon forgot in 1960 and Gore forgot in 2000, huh?), but don't tell the Trump deadender wackos that.
They've just been pressuring Pence to either side with Trump or prepare to be destroyed before the 2024 wacko primary whether Trump is running again or not.
If Democrats win control of the United States Senate by going two-for-two tonight (resulting in Vice President Harris becoming the 51st vote in the Senate) in special elections, they thus empower Biden to enact more of the people's agenda and confirm his cabinet and judicial appointments.
