Political hoardings everywhere!

Tens of hundreds of such hoardings (many of them being very large in size)are seen almost everywhere in Mumbai and Navi Mumbai. Most of them are either self-congratulating (e.g. 'Congratulations to ABC for winning in the election') or wishing the public on some festival (e.g. 'Happy New Year to all by ABC party').

It's the wastage of public money, at the end. Shouldn't there be regulations on the usage of such media of advertisement by politicians?
