"We" in this context is the collective nation of South Africa. We need to vote a different party to the presidency as the ANC is not working out.
Seeing as 30 years or so have passed since the end of Apartheid a lot of voters are actually young and won't vote for the ANC "just because" as they have no memory of any struggle.
I think the next election might be a close one. A lot of voters are dissatisfied, especially since 2020.
And the DA are running with the "Vote DA to end loadshedding" angle, and loadshedding affects us all.
The ANC is due for a wake-up call. They need to lose a general election.
