Enemies increase in political positions only when the people are not in your support.Most candidates use their powers to win an election and when an election has been won by a candidate that used his/her influence the hatred by the masses increase since the election wasn't free and fair.
I won't call politics a waste of time because it's a game that every political candidate knows before participating in it.Winners of politic position will you call it a waste of money every candidate knows that it's either your winning or losing the game.
That's the risk of playing politics your life will be at stake by haters,so before going in politics your security should be tight.
