There's no issue with coalitions per se, but there is when one of those parties was instruamental in saddling us with the current kleptocracy and they themselves are implicated just as much in kleptocracy as well! Do you honestly think the DA will win votes from the EFF in the next election or will it likely be vice versa? They are philosophically incompatible but the DA has actually helped the EFF get traction and the EFF has made no bones of the fact that they're only in bed as long as it suits them. Time to smell the coffee........
