Renugacharya is a BJP MLC from Karnataka. Recently he made headlines for having illicit relationships. Because of these people only CPM is not in the government.. It is a principled stand that where the party cannot influence the policies of the government, it will not join the government. That is why CPM participates only in West Bengal, Kerala and Tripura. Though many opportunities came in the way, CPM did not participate in the governments. Is there any other party like that? And compare this and the BJP that occupied the power for 13 days even when they were very sure that they had no majority.
