Always prefer mid-term election than procrastrination.But simultaneous election to both parliament & assemblies is mandatory.

If an elected govt.thinks that it can't stay & run anymore or it will not stay & run power in next term through present parliament/assembly,it can dissolve & call for mid-term election the very next day. Govt.may reflect people right.People may elect govt right.There is possibility that opposition members in parliament/assembly may not be right in present term.HENCE MID-TERM ELECTION IS ALWAYS PREFERED THAN PROCRASTRINATING WORLD ISSUES. But simultaneous election to both parliament & assemblies is mandatory to avoid wastage of public money.
