Labour have dropped to 17% because their left wing has moved to the greens, Libdems and nationalists. Reform support has stopped growing at 25% and that's mainly Tories moving across. The only people that harp on about "two tier Keir" are the extreme right wing loonies.
Absolutely. Labour betrayed their core voters, who are looking for something else, but won't touch Reform UK because they're even more disgusting than the current right-wing Labour-in-name-only government.
