I shall try.
They don't deserve to win because they are out of touch with the electorate, have communicated poorly and have a very poor leader. They have not recovered since Brexit and remain too factionalised between left and right. The grass roots have much to answer for and need to be reorganised and modernised.
As I have said, I am not voting for the party, I am voting for the best local candidate who happens to be Conservative. If it were a different candidate I may have voted LibDem.
I don't have a crystal ball so can't comment on their policies
What I do think, however, is that Blair in 1997 was handed an economy in good shape. This was delivered by the Conservative government and it allowed Blair's spending spree and supported his popularity wave. He went before the wave broke leaving Gordon Brown with a bit of a mess, so Gordon sold all the gold at rock bottom.
Labour handed over a bit of a mess in 2010 and the financial crisis meant austerity was inevitable. Cameron and Blair occupied the same space - both moderate populist who managed to hold their parties together. Neither were true conviction politicians. Their parties have respectively been picking up the pieces since. Both men and frustration with them allowed the extremes in their party to pull through. Corbyn and Johnson.
Bearing in mind that Starmer will have an economic mess handed to him alongside a huge majority, without Blair's charisma in his back pocket, Labour will not take long to factionalise and will quickly be attacking itself from within. It is likely to lose favour pretty quickly and middle England will squeal as its pay packets slim due to increased taxation and unionised industry payclaims. Things will quickly turn ugly.
In my view I'd like to see a new, moderate centrist party come through, not unlike the SDP. I think the country needs something new but it isn't Labour and it isn't Conservative. It presently doesn't exist.
I want a free market, a safety net for those who can't rather than those who won't, significantly improved education and the erosion of massive one size fits all comprehensives, personal choice and freedom. Personally I think the NHS has to go in its current form and the medical profession needs to modernise and jump into the middle of the 21st Century. Defence is critical and providing young people with the skills to navigate life rather than the EBacc for all which has fuelled inadequacy for the non academic and ramped cognitive dissonance.
I don't have a massive issue with immigration for as long as this country allows those for whom there's ample work to decline to work more than 16hpw to retain their universal credit. I haven't been able to get an English cleaner for about 30 years and in London and the South East the going rate is £17/£18ph.
