Dear Statalist users,
I have created a panel dataset based on election results (this is a fairly large dataset across 8 elections and I have only including a small portion of 3 election cycles here)

This is election data for different villages in the city of Mysore, from state Karnataka with the name of the winner and number of votes received.
I need a panel that has a unique id for different villages, along with election winners over the years. However, due to variations in the spellings of the state, city and village, I am not able to think of a tractable way to do this.

Thanks!
