Mandatory Democracy?

Thanks to Mumbai's poor voting, barely 40 per cent, few political leaders have demanded voting be made mandatory. Well, how do you enforce it? By getting the abstaining voters arrested or withdrawing basic facilities from them or making them pay more tax and money?
Voters understand their rights and would always like to exercise provided they benefit from this. How their expectations are met? With more and more lousy promises? The terror trauma of 2008 will take time to get erased. This can only be done by politicians becoming accountable--offering concrete solutions rather than mere promises.
We are not supporting abstaining voters; we are only trying to analyse this most serious trend for the largest democracy of the world. Trying to enforce democracy would be the joke of the millennium!
Before making such demands so-called leaders should first introspect, introspect intensely.
