Voting can be a tool, but not really beyond cases like Hungary where it has been allowed to persist for long enough that the autocatabolic nature of fascism burns out the population at large (so pretty much allowing it to run its course, with some limits imposed by the EU in this case) and not having the ability to look for fuel beyond their borders.
Fine if the spread of the fires can be contained in such ways, not much use for more than ruling over the ashes otherwise.
Edit: To clarify, it requires these conditions (the former to be effective, the latter to actually matter) because otherwise the people who cannot be compelled to do anything beyond voting will just meekly sit by as the vote gets ignored anyway, so long as the fascists have enough of some form of power to maintain the momentum to do so.
