I don't see it. Most people outside India do not have enough interest in India's politics to want to spend enough time to develop a nuanced understanding. I don't see the value in people in other countries develop, for lack of a better word, a "John Oliver" level of understanding of my country's internal affairs.

That is almost entirely opposite the case with Modi though. Most BJP voters vote directly for Modi (and BJP's electoral campaigns reflect this) because they like him and have trust in him, even if they don't particularly like/care about the local candidate of BJP. Modi has been quite successful in turning Indian elections quasi-presidential. Forget general elections, BJP goes even into state and even local municipal elections asking for votes in Modi's name.
