The BJP has run a high-pitched campaign against the Left Front government to unseat Mr Sarkar whose coalition had won 50 out of the 60 seats in the 2013 assembly polls including 19 out of the 20 seats reserved for tribals. The BJP has all of six lawmakers in the state assembly; all of them had switched over from Mamata Banerjee's Trinamool Congress a few months back.
"He is extremely popular. Since 1998 when he became chief minister, he has tried to improve the lives of the tribals" said Surest Debbarma, a CPM supporter from Takarjala, a tribal hamlet.
His clean image may be the key to Left continuity, but even his comrades agree the upcoming elections would be a difficult race.
"The fight is bit different than earlier, so we have also changed our strategy" said Subhash Deb Nath, another CPM supporter.
Mr Sarkar has been BJP's solo target for an alleged job scam, unemployment and blurred lines between the party and government.
Some others in the opposition don't have any doubts about Mr Sarkar's honesty but claim his government is tainted.
"As a human being he is honest, but as a CM he is presiding over a corrupt government," said Tripura Congress Vice President Tapas De.
BJP's poll war cry of for Tripura polls has been 'Chalo Paltai' or 'let's bring change'. Perhaps what now stands between continuity and change is the image of CPM's poster boy Manik Sarkar.
The Tripura polls are slated to be held on February 18 this year the counting for which would take place on March 3.
