I'll be honest Gotta, I do not understand half of the gibberish you've written.
However what is clear is that you understand even less about international politics than you do the UK.
Sanders had no chance, the Democrats knew this, which is why they went for Clinton. The shambles that is the electoral college system cost Clinton, winning the popular vote is hardly a rejection of the centre left.
The French election is between the the centre left and the right wing. The left wing were left trailing in what is a socialist country.
On another thread a few weeks ago some other Branch Corbynian said watch out for Melenchon before the 1st round, as if there were some left wing resurgence going on. Strangely enough that didn't happen, and Melenchon's sole contribution subsequently has been to say he won't tell his supporters to vote for Macron. When the alternative is a fucking fascist!!!
The extreme left and right have one thing in common, that the majority of the centre think both extremes are ideological arseholes you wouldn't want to be stuck alone in a room with.
The majority of people don't care about ideology when they vote - they care about their own lives & what Govt they think will be best for them personally. Until they get affected by something personally, a reasonable majority will put up with weaker/poorer members of society getting fucked over by the Govt, providing it's not affecting them. Why do you think the Tories have managed to win elections (& will win again) despite being on an austerity ticket?
Voters care about the economy, and along with appalling leadership, this is where Labour fails most. Corbyn & his front bench of inadequates (with maybe the exception of Watson and Starmers) couldn't run a school fete, let alone the country. It's for this reason that I cannot vote for Labour for the first time in 25 years (although I will not vote Tory either).
Come 9th June all those blindly following the cult that is Corbyn should hang their heads in shame for what they've done to the Labour Party & burdened the rest of us with 5 more years of the Tories. But hey, you can all cheer yourselves up watching some more Ken Loach poverty/misery porn and say how cruel & unjust the world is taking no account for your actions.
