How often does a politician lie?
Answer: Every time they open their mouth!
It is only by one being a good liar and cheat that they will be a good politician, so, the more they lie and cheat, the better the politician they are!
So, this is why Paul gives the injunction in 1Tim 2v1-8 that we pray for
ALL in authority, so even though they lie and cheat while in government, God over rides there evil and brings good forth through during their time in office...
Politicians...who would have them!
