My answer is questions. I'm sure as an economics major you are very analytically minded. Have you written down the pro's and con's? Do you have to be an elected official in the limelight? Can you be happy being the Chief of Staff, Chief of Constituent Affairs, or some other high ranking title in an elected official's staff? Why do you want to be an elected official? What do you hope to accomplish? What other positions are there where you could accomplish the same thing without going to law school? What percentage of elected officials are not lawyers? Is the trend towards more or less lawyers being elected? If you do not feel strongly motivated to go to law school, will you be able to apply yourself to the rigorous studies for 3 years? Do you know how much debt you will incur? What type of law do you plan to practice while working your way into an elected position?
Okay, I think that's enough questions! Personally, if you do not feel it calling you, I think it will be difficult. But, if you really feel this is the path to where you want to be, then go for it. But, please, seriously consider some of the questions I have posed!!
