In ancient India, Durga was defence minister and Laxmi the finance minister: V-P Naidu

[Samudra Manthan]

So why aren't they ministers now? Have the gods/goddesses abandoned India after seeing sanghis using them for votes?

No the gods/goddesses have not abandoned India and nor do they mind being used. Being of use is one of their primary functions and a Hindu understands that. Being of no use to anyone is what a commie Bengali is.
