Removal of presidential term limits starts with the seemingly lone voice of a sycophant or ruling party hack. This is met with denials from powers that be. Then another voice makes the same call. More denials come from mainstream party officials.
As this back and forth continues, the agenda begins to move from the fringes of party debate to national centre stage. The proposal is then taken to political rallies and media. Then full-blown state-aided mobilisation in support of the proposal begins. By now, removal of term limits is a central agenda of the state and ruling party.
