I would think that a grounding and exposure as a farmer or an artisan, and a functional literacy, and a commitment, need to be the essentials for leadership for this country.
Those grown up in affluence and in public schools, and schooled in intricacies of fourier transforms or management theories are deeply alienated from the people. If they desire, they may be clerks to the actual leaders who need to be from the people. Literate, and preferably most rooted in the local language.
Tejaswi himself said, dot judge a book by it's cover. Isn't that enough articulation in an elite friendly language?
When Rohan Murthy can be accepted in Infosys, I'll accept Tejaswi as a minister in Bihar. He's privy to one of the most brilliant political minds of India.
He is not good or bad, he's just political.
Meanwhile the brilliant mind of Modi & Shah put up posters of cows in the 5th phase of the Bihat elections held in 4 eastern Bihar districts with high Muslim population. Muslim radical Owaisi also put his best efforts in that phase, both got the rightful thrashing by our politically savvy RURAL Bihar folks.
