Yogi Created History?

Yogi Adityanath, CM of UP has created history with the thumping majority. Sources say he has achieved this after 37 years to return to power after completing his first tenure of five years. Though before this four CMs returned to power but none were in the position for full five years source says. Late N D Tewari was the last CM of undivided UP in 1985. Before this, Late Sampurnanand in 1957, Late Chandra Bhanu Gupta in 1962, and Late Hemwati Nandan Bahuguna in 1974 continued the second term without completing it?
