Genetic monstering?

Is there some sort of gene which politicians have to let them lie shamelessly and look offended when no one believes their crap? Take the Indian government as a prime example. They’re denying that British overseas aid paid for the satellite, which they have just parked in Mars orbit. But there’s no denying that our money went into their overall budget and if they hadn’t had it, they wouldn’t have been able to afford the satellite. So we paid for it. No question.
