They beg us for votes and then tell you to go f**k yourself when they get elected. Thing is that they keep doing the same thing over and over and people keep voting for them. Some of us learn the first time, while others just don't get it.

More annoying is that so many people pledge allegiance to one party or the other and then, in spite of centuries of evidence to the contrary, choose to believe, even to defend, those lies.
