Abstract

We present a spatial map of the Italian House of Deputies during the XIII Legislature obtained by applying the Poole and Rosenthal methodology to roll call data. We estimate coordinates for almost all the 650 Deputies that were on the House's floor at the time, and we aggregate them according to parties. We find that voting patters generate basically a two dimensional political space. The first dimension represents loyalty to either the ruling coalition or the opposing one. The second dimension is represented by the European Union. These findings are consistent with the exceptional case of the party Northern League, which at the time did not belong to either coalition, and presented itself as a northern, separazionist, and anti-system party.

Keywords: political space, left-right, italian parliament
