Two positive impacts of casteism in Indian politics are as follows :

 i. To bind the people with one string : 

The relation of caste and politics has bound the people in a stream. People of the same caste even while living at remote places, come into contact with each other in meetings held by the people of their caste. They maintain contact with each other through modem means of communication. They help each other in resolving their problems and try to maintain unity among the people of their caste to take greater advantage from the government. This develops the feeling of unity and social cohesion among the people. 

ii. To generate political activism : 

The caste-based politics has enhanced political activity in a big way. People have started becoming active in politics to keep their influence in their caste and to protect their interests. They have begun to get involved in social work. The active people of ethnic organisations have also become active in politics.
