My interpretation of 2020's surge in turnout is that it suggests a much less stable electorate than we have come to assume.
The INC/BJP-esque dynamic between the Democrats and Republicans hardly suggests that the former are guaranteed a happy electoral future - the relevant ethnic majority here comprises two-thirds of the electorate and is permeable enough to admit many members of other groups - but that's hardly the only salient comparison.
I'm not as familiar with Indian politics, but this post made me curious - is there a similar gender disparity between Indian parties as you see in US politics, and if so, does it vary by region?
It's quite difficult to explain the intricacies of Indian politics in a nutshell but in a simplified manner the BJP blends nationalism and religion to appeal to the roughly 80% of the population that is Hindu while the INC, a shell of what it once was, uses dynastic politics and appeals to secularism to appeal to religious minorities (read Muslims), a decent chunk of Hindus and a hodgepodge of other groups. Note that this generalization does not take into consideration caste, north v south divide (BJP has limited inroads in the Dravidian non-Aryan south, language politics (Hindi imposition onto non-Hindi speaking states), the demise of the Left Front, and regional political parties, etc.
Averroes point is that the BJP/GOP appeal to a majority group of the population while the INC/Dems appeal to a collection of various minority groups to form a larger coalition
