For 68 percent, more than 2 out of 3 Italians, Silvio Berlusconi is the man who more than any other, positively or negatively, has marked the history and customs of our country over the past 40 years. This is the most significant fact that emerges from the analysis conducted for the television programme Otto e Mezzo (la7 channel) by the Demopolis Institute. Berlusconi remains, for better or worse, the most singular personality on the public scene. Forty percent believe he has contributed to radically changing society, while 51 percent think he has intercepted, represented and amplified the change that took place in the country between the 1980s and 1990s. According to Italians, the former Prime Minister has marked Italian society mainly through commercial television, as 53 percent say, but also - 35 percent are convinced - through his presence in politics since 1994. It is a combination that in language and style - according to the Demopolis Institute's Political Barometer - has increasingly shaped the Italian political system in Berlusconi's image. In recent years, Berlusconi has often divided Italians and public opinion's judgment has always remained largely polarized according to voters' political positioning. In the memory of Italians about Berlusconi's nearly 30 years of political activity, first and foremost, the ability to unite the Center Right with the initiation of bipolarity starting in 1994 remains imprinted. But also the new language and the showmanship of politics, cited by 48%. Forty-four percent recall judicial affairs and clashes with the Judiciary, about a third the reluctance to rules. For 33% it remains Berlusconi's ability to seduce part of Italian public opinion for nearly 30 years.
