Yes, with a well-designed state machine definition, you can model a voting scheme to meet the requirements you need. For example, voters can publish vote events as transitions, or in any other way. The state machine can base its state transitions on a period of time during which voting is open. Once that time passes, the state machine can change its state to "counting," for example, and finally to "closed" once the counting process is finished. There are many different ways you could model the voting process, but you can certainly model it as a state machine.
