As I already said I agree with your comments on Corbyn but the choice was between Very bad and dangerously bad, Corbyn being the dangerous one. Boris the incorrigable inveterate, opportunist liar can't be trusted. As for being a patriot, I presume you are referring to Brexit, well Boris was a staunch remainer under Cameron until the referendum. In fact Cameron was astounded by his sudden change of stance.
May got herself elected to carry out Brexit after voting against it and Boris saw his opportunity to jump in knowing May would fail.
Neither Johnson nor Corbyn could be trusted with a rational person's vote.
It's like being given the choice of "How do you want to die, by poison or a bullet" with those two. No thanks I'll vote for old age.
