Yup, that is exactly what happened in Germany in the 1920s-30s - the National Socialists and Hitler were 'democratically' elected, and went forward to subvert everything. But I would say that just because a group can subvert the rules and institutions of democracy once in power, that they are still a small-d democratic regime because they were initially elected and followed some of the forms. E.g., Putin just won his elections, but only after he put his primary opposition in jail...
