These state-wide series of meetings involve supporters of each candidate attempting to convince those who attend to choose their guy. But at what point does the process of convincing become cajoling? Who has time to spend hours at a meeting – surely only the well off? A secret ballot, as used in primaries, guarantees the voter freedom of choice, free from any political pressure. No such luxury is afforded at caucus meetings. In Nevada, we had the crazy situation of most of the meetings being held in casinos, where workers belonging to an Obama-friendly union do most of the organising. As a side point, Obama must be worried that this set up still led to his defeat, while Clinton can claim the moral high ground.
