Brahmin become P.M. for most of the time........55+ years out 65 years because Most of the front-leaders were Brahmin in early days. But that is not the situation today. MMS and Modi are 2 examples. Even Nitish, Mayawati, Mulayam are not Brahmin.
Karnataka - Sadanand Gowda - OBC
M.P. - Shivraj Singh - OBC
Bihar - Sushi Kr. - OBC
Jharkhand - Arjun Munda - ST
H.P. - Prem Kr. Dhumal - SC
Chattisgarh - Raman Singh - Thakur
Gujarat - Modi - OBC
Uttrakhand - Khanduri - Brahmin (But because 50% population of Uttrakhand is upper cast. Since, Cong CM candidate is Thakur (Rawat). So BJP candidate is Brahmin)
If in future BJP comes in power in Delhi, Rajasthan, Goa, Maharashtra, U.P. - It will be Non-Brahmin.
