    Implement a project which will be an online voting system. By using different aspects of socket programming. The network type will be client-server. The client-server connection will be implied by the TCP protocol. The server should create a new thread for each new client that connects.

You should allow voters to change their votes till the deadline. Also, implement the feature where a voter may independently login and participate in multiple and different voting instances.
