He has to wait to see what he will hve to deal with- after those Tories have made a massive mess of the country. he knows he must not make pledges that can't be fulfilled. It is wise to wait.
But THE FACT is, that divided Labour, with a far left leader, cannot and will not win, for all sorts of reasons. People have changed, aspirations have changed- and because of the FPTP system.
So, again, if the ONLY choice is between far right as now, and centre left with Starmer- you would prefer Tory ERG far right to continue? if that is the case, then what can I say? Despair.
