The leader arrived, wearing a mask decorated with the Italian flag, at a polling station in Milan and said he was confident his coalition, composed by Giorgia Meloni's Brothers of Italy and Silvio Berlusconi's Go Italy! will win in the regional election.
"I am confident that tonight there will be more center-right governors and councilmen than last week," Salvini told reporters.
The center-left is expected to lose control of Marche in the center and Puglia in the south, while holding on to the southern region of Campania. Tuscany looks like a neck-and-neck race.
The right should easily keep power in the two northern regions where it currently governs -- Liguria and Veneto. The seventh region at stake is the tiny, French-speaking Valle D'Aosta which has its own party system.
