Trisher, all the info about Johnson was in the public media. I read articles from his first employer about his making up stories to file with the Spectator because he was too lazy ( or up to other things) to research articles. For every anti Corbyn article there was an anti-Johnson one, he came out as just as unpleasant and untrustworthy as Corbyn.
The choice in this last election, as far as the leaders were concerned, will be seen in history as having to choose between the two most despicable men who have ever fronted the two great parties and you had to hold your nose very tight to vote for either.
In the end, the electorate as a whole, including a lot of traditional labour voters decided that Johnson was the lesser of the two evils and voted for him.
There is nothing more ludicrous than a party that lost, not by a whisker, but by a landslide claiming that its policies, ie the manifesto, was very popular with voters and their leader was also popular on the doorstop. If that was the case why didn't you win?
The Labour party has been very active since blaming the media and Brexit for its problem. The one phrase I didn't hear was that they had been talking to the voters, especially those who used to vote Labour, and asking them what the problem was. It is possibly that they have and they do not like what they have heard,, or rather it doesn't match their own story, so they are ignoring it.
