Campaign For this election Berlusconi ran again for Prime Minister as leader of the
centre-right House of Freedoms (), which included the
Forza Italia,
National Alliance,
Northern League,
Christian Democratic Centre,
United Christian Democrats and other minor parties. The candidate for Prime Minister of the
centre-left Olive Tree () was
Francesco Rutelli, former
mayor of Rome. On the television interviews programme
Porta a Porta, during the last days of the electoral campaign, Berlusconi created a powerful impression on the public by undertaking to sign a so-called
Contratto con gli Italiani (), an idea copied outright by his advisor Luigi Crespi from the
Newt Gingrich's
Contract with America introduced six weeks before the 1994 US Congressional election, which was widely considered to be a creative masterstroke in his 2001 campaign bid for prime ministership. In this solemn agreement, Berlusconi claimed his commitment on improving several aspects of the Italian
economy and life. Firstly, he undertook to simplify the complex tax system by introducing just two tax rates (33% for those earning over 100,000 euros, and 23% for anyone earning less than that figure: anyone earning less than 11,000 euros a year would not be taxed); secondly, he promised to halve the unemployment rate; thirdly, he undertook to finance and develop a massive new public works programme. Fourthly, he promised to raise the minimum monthly pension rate to 516 euros; and fifthly, he would suppress the crime wave by introducing police officers to patrol all local zones and areas in Italy's major cities. Berlusconi undertook to refrain from putting himself up for re-election in 2006 if he failed to honour at least four of these five promises. == Main coalitions and parties ==
