As I get older, and My God 78 is old, I gain wisdom and clarity in observations.
I'm not a fan of two of these leaders, know little about the third since cricket and like and admire the fourth, but my personal feelings have nothing to do with this.
Nobody is perfect. Even my alltime hero, Charles Dickens, was apparently a shit to his wife.
And it seems the better someone is at some things, the worse they will be at others.
The problem is people failing to see beyond their natural instincts.
Example: for all his faults, the only one of the four I think would be an excellent dinner companion is Johnson. But that doesn't stop me seeing his faults.
Trump showed he is brilliant at using the system, manipulating the media. Like the Brexit lot, he knows the value of a simple slogan. In fact I think he's shown himself to be better at that than almost anyone else (he did get elected, after all).
His faults are also massive. But he was not a disastrous President.
Likewise Boris who has achieved great things (becoming PM; becoming Mayor) yet is clearly awful at others (like telling the truth or even masking his version of the truth).
Corbyn was a terrific Leader of the Opposition; calm, sensible, making excellent points - far better than Starmer. And he got elected Labour chief. But listened to the wrong people and failed to beat the media and his enemies (anti-semite? Bollocks).
Nobody is perfect. So don't fall for the media hype - one way or the other.

I reckon the Republican Establishment are hoping this will rid themselves of Trump.

As for Corbyn..10-12 million votes and 2.5million Twitter followers...too early to write him off or a younger version who will appeal to millions of under 40s.
