Tunisia under Saied has become an authoritarian state, as he dashes the dreams of democracy that the country had after the Arab Spring. Since coming to power, Saied has made blatant power grabs and has consolidated his control over the country, with these disqualifications and arrests of opposition figures being prime examples. These upcoming elections will be neither free nor fair.
Saied's reforms were desperately needed to ensure the country doesn't fall into the cycles of violence and stagnation that preceded his rule. The widespread acceptance of these reforms is perhaps reflected in the inability of opposition figures to garner signatures without resorting to fraud, while they make baseless claims of obstruction. The noise made by the opposition is clearly sour grapes.
