Shockingly, I agree with you. Anyone who wants to get into politics is most likely a power-hungry narcissist and should be immediately distrusted. But I have a feeling that if we don't choose someone they'll choose someone for us and I would like to have a modicum of control over this decision.
And I'd like to know that someone with a say this shit isn't going absolutely balls-to-the-wall jacked up on a power kick.
