Double majoring or not?

<p>I hope some of you could give me a good feedback regarding my issue.</p>

<p>I'm a student that is seeking a Economics degree, but I would like to double major in political science. This might sound ridiculous, but I would like to be a Senator or President. Do you think that it will be a good option to follow this double major, or to finish my BA in economics, then do a Master in Political science and PHD in Econ?</p>

<p>What are your suggestions.</p>
