It's simply not anyone's problem other than your own that you don't keep up with politics.

Nor do you seem particularly observant when it comes to the news. Did you not hear about the incident at camp this Summer? A few rowdy students caused a food fight that got out of control. Many of them ended up in St. Mungos, and one lost an eye. Dumbledore was in charge of this, and yet he did nothing to prevent it from happening.

How, then, is that a sign of 'good decisions'?
