He knows he's lying and so do his henchmen, he just doesn't care. You can see it in his eyes when he's lying and when he's totally clueless about how to answer a question, he goes on auto, 'Get Brexit done'...'I've only been in power for 120 days...blah, blah', same old, same old.
We were led to believe that he is some sort of super brain. Highly intelligent they said. Well someone said anyway. He hasn't shown the slightest sign of being highly intelligent.
Would a truly intelligent person make such appalling speeches or repeat set answers repeatedly, and worst of all, shy away from significant climate debates and BBC interviews? Apparently he was at a farm shop in Devon and couldn't make it to the climate debate.
For all his bluster, he is an incompetent campaigner. Some of the original contenders for the job as leader must be smarting when he's put on the spot with questions he doesn't like, and simply refuses to engage. He is the master of crass remarks and blatant lies.
