I disagree.
For one, lots of people don't trust the MSM, not least reform voters. I don't believe that pointing out that best case is that he has honest intentions but is an incompetent grifter and puppet for Trump would have any impact.
As someone who has never voted to a party for the right of the Lib Dems, and more often voted labour, I can certainly see that there are a lot of people out there like me.
Not impressed with labour at all, not least their failure to be even vaguely centre left in economic terms, their hatred of free speech and their TQ+ / woke elements which have far too much power.
Tories - useless by their own standards, and I don't like their standards.
Lib Dem, greens - Total woke / TQ+ nonsense.
As someone who is left wing my choice is really "vote Reform because at least they seem to be quite anti TQ+ / woke, and they might actually try to do a tiny bit to address excessive immigration and islamism" or "don't vote because they are all totally appalling".
Also, in terms of population / economic growth. On the one hand you are right, we need immigration to boost the economy and do jobs we need doing. On the other hand it is blatantly completely unsustainable and anti- what the British population want to continue with the pyramid scheme we currently have, whereby government debt rises, productivity stagnates, and we have to increase the population to pay the increasing debt and look after the elderly (just like in 50 years the same thing will still be happening). People - even if they can;t express it clearly - understand that this is an issue.
