The presidential campaign, featuring 25 competitors, kicked off in early November and it's the first time since Tunisians overthrew dictator Zine El Abidine Ben Ali in 2011 that they will choose their head of state through universal suffrage.
If no candidate wins a majority Nov. 23, there will be a runoff between the top two vote-getters on Dec. 28.
Alone among the countries that experienced the Arab Spring uprisings in 2011, Tunisia's transition has remained on track.
After 3 1/2 years of a stormy transition marked by high unemployment and terrorist attacks, Tunisians voted for Essebsi's party Nida Tunis (Tunisia's Call) hoping to bring back stability and prosperity.
Essebsi started his campaign in Bourguiba's coastal home town of Monastir and evoked nostalgia for this towering figure of Tunisia's history who won independence from France and created a modern state defined by a well-educated middle class albeit with little room for dissent.
"There are many fears of the return to the one-party state, of course," said Michael Ayari, Tunisia analyst at the International Crisis Group. "There is a fear of returning to centralization, a single 'pater familias' (head of the household) who will become an omnipresent figure."
Despite his age, Essebsi has been campaigning vigorously all over the country to packed stadiums, and Saturday night was no exception in the Tunis neighborhood of El Menzah, where a giant screen was set up for the many supporters who couldn't enter the thundering stadium.
"We will not exclude any party," he told the crowd, and addressing fears that his victory could usher a new era of one-party dominance. "Just as we reject violence, we are against exclusion," he said.
Following their parliamentary election loss, Islamist leaders, many of whom were once imprisoned by colleagues of Essebsi, assured their rattled supporters that a police state was not returning.
