Now get this—early voters will not attend the caucus so their vote is final.
However, voters who attend the day of the caucus can re-align to make another candidate viable.
The FAQ does not indicate whether you can switch more than once, whether you can switch from one viable candidate to another candidate, and how it is determined when the musical chair music stops.

That’s a feature not a bug. It gives the rats cover to cheat “independent Bernie” out of first place.
