The second change is that, after almost two decades of striving for a workable political system dominated by the center-left and center-right parties, Italy is experiencing a remarkable dispersion of forces. The ballot will include dozens of competing parties, most of which will not win parliamentary seats, owing to a 2005 electoral law requiring at least 4% of the national vote to enter the Chamber of Deputies (the lower house) and 8% on a regional basis to enter the Senate.
其二是在为建立中间偏左及中间偏右政党主导的可行政治制度奋斗近二十年后，意大利的党派力量正在逐步分散。几十个竞争党派将参与选举，其中多数因2005年选举法规定至少要4%的全国选票才能进入众议院（下院）及8%的地区选票才能进入参议院而无缘赢得议会席位。
