how to use json data in website, what kind of database should I use?

I am trying to create a website in which a visitor can click a state in the US map and it gives you a statistics and information about the candidate that ran in the state's election in a given year. I already have a image map and I will add a java script function that takes year and the race's district as arguments.

I am trying to do this in django and Google App Engine and I mainly code in python.

I have put gathered and put together those data in .json file thinking that I can do something similar toopen("path.json", "r") in python and just pass the data. But I am not quiet sure how do it to and whether its even possible to do such thing. As I did some googling, I am starting to wonder if I need to use database. Should I use database and if I have to, RDB or NoSQL? In addition, how should I feed the data in json to the database.

json file looks like this
