"Both parties are the same people" (in general) are just lazy slob fucks that refuse to use their brains to understand politics and study history, and would rather jerk off during election night to hentai porn and continue to play call of duty and eat cheetos than go out, exercise their civic duty and cast a vote. And whenever someone starts sounding smarter than them when discussing the parties/candidates, their brain goes into defense mode and they start belittling them with the same tired canard.
Grow the fuck up. It's because of this attitude that Gore and Kerry both lost, and democrats continue losing midterm elections.
