Uttarakhand goes to polls on February 15 in a contest where both the ruling Congress and the BJP will battle for 70 seats. The test will be crucial for the Congress, which has been in power since 2012 but has yet produced only one chief minister who has lasted a full five year term. The last and only chief minister to have lasted a full five year term was ND Tiwari, a Congress chief minister with a term from 2002 to 2007.
