Eh, well... Italians.
Post WWII, they set up a system that favored small parties -- so was guaranteed to fragment, fall apart: by the '70's there were 17 political parties
, and a constant squabble of coalition governments. So they "fixed" it sometime around 1993-94... by which time they had a "tradition" of very short-lived governments. And around 900 or so members of parliament for a population of about 60 million.... And they
will go on electing Berlusconi.. Not a poster child, but not typical, either.
