Does that mean Trump's lies are ok?
It must, since we all do it every single day.
If you lied repeatedly in order to deceive your boss you'd be fired or at least in big trouble. We're the boss of these politicians.
First, I don't have a boss. I am the boss. People change the context of things to make themselves look good all the time. They shift blame to make things not their fault. Outside of Donald Trump, most political 'lies' fall into this category. If you actually possess the ability to be even a little bit introspective, you'll realize that you do the same things that you slander politicians for.
