Regarding those who are calling out the alleged Sharon D. Clark loss to Joquina Kalukango an upset, this definitely comes down to voter having to see all performances in order to vote in a category. Caroline or Change played during the peak of Broadway covid, so I can imagine many voters skipping it. Then the announcement of the upcoming revival of Death of A Salesman, that would in previous years likely create a bandwagon effect for voters, especially for those who didn't see the production wanting to support the upcoming Death of a Salesman revival by casting a vote for Clarke. I didn't see Clarke's performance, but Kalukango is not undeserving, she is the saving grace of the mess that is Paradise Square. The fact that Kalukango was able to give such a powerful performance with such weak material, where her character is sidelined for much of the second act then reclaims the show with a roof shaking eleven o'clock number is most definitely awards worthy.
In truth this debate is an interesting one, what is more deserving of an award:
a) a great performance of a meaty well written iconic role
or
b) an mesmerizing performance where an actor elevates weak material
In my opinion if the performances are even slightly on par with each other, I would award the later for the amount of work it takes to accomplish such a feat, especially in the leading actor/actress category where they have to carry the productions on their backs.
