Can this man save our country?

Matteo Renzi, the actual mayor of Florence, announced is intention to govern Italy. He will attend the internal competition of the democrats to become leader of the party. Renzi is one of the youngest  politicians and he will have the chance to beat Pierluigi Bersani, the secretary of democrats, and to challenge one between Angelino Alfano, ex Minister of Justice, and Silvio Berlusconi.  Renzi is trying to represent something new in the Italian policy but the question is if the voters will believe in him.
