My vote - Kamaraj
1. Embraces rhetoric of "Sacrifice" and austerity
2 Populist to some extent
3. Believer in "Efficient" Govt as force for good
Partial to big welfare schemes
4. Not much subaltern anti-UC rhetoric
Both of them single men with no kids. Public valued their personal austerity the most, and "incorruptibility" was their biggest USP
But then Modi uses secular rhetoric a great deal after his ascent to national prominence
Except for their attitude on the "Other", I see striking similarities
