One of the roles of the Vice President of the United States is to count and announce the Electoral College vote at the end of a Presidential term.
Every Vice President has done so, constitutionally, in modern times, even when the Vice President may have been the Presidential nominee for the next term in office.
So we have Richard Nixon in 1961, Hubert Humphrey in 1969, and Al Gore in 2001, who have played their proper role.
Also, Walter Mondale in 1981 and Dan Quayle in 1993 were on losing tickets as Vice Presidents, but played their proper role.
And Dick Cheney in 2009 and Joe Biden in 2017, both leaving office, did their duty!
Finally, after much hesitation and the intervention of Dan Quayle led Mike Pence in 2021 to do what he was required, constitutionally, to do in his role as Vice President!
Many groups and individuals, including those who are clearly conservative in nature, argue that the Electoral Count Act of 1887, enacted a decade after the disputed Presidential Election of 1876, and two close elections in 1880 and 1884, needs to be overhauled to prevent the crisis that occurred in 2021, only prevented by Mike Pence, at the last minute, following his duty, despite threats to hang him or murder him by mobs engaged in the US Capitol Insurrection on January 6, 2021!
