Express News Service DEHRADUN: Changing chief ministers midway through a term has not helped any party in Uttarakhand. Analysts are calling the BJP’s latest move a gamble. Dehradun-based political analyst Yogesh Kumar said: “Apart from ND Tiwari, no CM has been able to complete five years, either due to circumstances or intervention of the central leadership. Common factor is that both BJP and Congress failed to make electoral gains they expected by changing the CM. It’s a big gamble by BJP, with less than a year to go for Assembly elections.” Only one of the eight CMs in the state completed five years in office. It was the late ND Tiwari from 2002-07.
