I refer to the specific and general. People incl reportedly Tony Leon and Wilmot James - the last in an op-ed -said it's no longer a liberal party or those values are under threat. Then there's Zille's and De Lille's combativeness to questions about their purported omniscience. Zille's articles presume her to be a guiding light on governance and ethics but matters I brought to them and their administrations about serious violations were ignored and not acted upon immediately or later resolved as you claim happens. De Lille has threatened people who've questioned her w/ legal action, incl about controversial concreting over CT developments, as the WC government actual did to an employee whisteblower, which was thrown out of court when it reached there after a couple of costly years. 
And what about the DA's hysterical reaction to Zille's tweets (and I'm not a fan of hers) and Diane Kohler-Barnard and Maimane's/DA's frequent wishy-washy and PC stance? And their handling of water crisis?
