I agree, @ReggieHere. All potential successors need #Starmer to carry the can for wipeout on 7th May.
But will anyone be in a rush to challenge Starmer?
Streeting is ambitious but unelectable. Rayner is eager, but has baggage. Burnham is popular, but way overrated (good mayor, but twice-failed Blairite leadership candidate), and lacks a path to Westminster: can Labour win any parliamentary by-election now? #NoSafeSeats
Starmer may stagger on for a year or two, while Greens eat Labour.
