The Conservatives were always going to lose the last election - and were probably happy to do so. Having left the country in a total mess after 14 years of mis-management and underinvestment (or rather - having robbed every last penny from the public and handed it to their chums) they were happy to dump the whole shit-show into Labour's lap.
"Everyone hates Keir" - From Day One, there has been a concerted effort on the part of the Conservatives to conduct an ad hom attack on Starmer. Every day, for the next 4 years, you'll be reading headlines in the Express, Mail and Telegraph, seeing posts on "X", and getting Tory trolls posting threads on MN and elsewhere attacking Starmer.
"Reeves will destroy the economy" is the second prong of attack. GBNews proclaims that families will be robbed of 91% of their inheritance. The Mail ran a story about one family (theoretically) paying over 90% in IHT, only to reveal that the estate was worth over £4million - i.e one of only 100 estates of that size in the UK. For 96% of the population, IHT will have no impact whatsoever - and the other 4% can use various schemes to mitigate IHT, which the right-wing press have also been keen to promote as ways to avoid paying tax.
As for other taxes and financial measures - the Conservatives seem to have already convinced a large section of the population that it must have been "someone else" who was in charge for the last 14 years - something that they tried every time they changed leaders from Cameron onwards. It was always "the other lot" wot done it - never them. They still believe the twin lies that it is possible to have good public services without anyone being asked to pay for them, and that the Free Market will solve any and every economic problem.
As we've seen with Brexit in the UK, and Trump in the US, a well-organised and well-funded campaign can persuade people to vote against their own interests. Convince people that there is an "enemy" - the EU, "Immigrants", "Lefties" or whoever - and then use lies, slogans, stunts and foghorns like Trump, Boris and Farage (with a supporting cast of nasties like Tommy Robinson and Lee Anderson to say the worst things) to hammer the message home. "Repeat a lie often enough and it becomes the truth." If any opponents can be silenced, then all the better. The Conservatives and Republicans do this by controlling the print and broadcast media. Musk goes one step further, amplifying the right wing and banning any dissenters or opposing views on "X".
Will Farage and Kemi form the next government? It's perfectly plausible, although neither of these two chancers will actually be PM - Boris dreams of a Trumpian come-back, Mel Stride (Public School educated, Oxford PPE, typical Tory grey male stuffed-shirt) is already in place to keep an eye on Kemi, and Honest Bob Jenrick has morphed into a piss-poor Farage tribute act but clearly has the right connections and donors so can't be rule out.
