Would government prove a poisoned chalice for the Five Star Movement?

The formation of a new Five Star Movement/Lega government in Italy is in doubt after Italian President Sergio Mattarella refused to approve of Giuseppe Conte's proposed economy minister, Paolo Savona. Ben Margulies writes that if the Five Star Movement does enter government, the main risk for the party will come from the Italian economy. Should external factors, such as EU constraints or the bond markets, force the new government to implement unpopular economic policies, then the Five Star Movement could be in a particularly weak position given almost two-thirds of its voters cited economic reasons for choosing the party at the last election.
