They'll be throbby for much longer than a year and it’s hard to see them getting out of that cycle as the party members are increasingly electing more throbby candidates. The grass roots are at an all time low membership level and they too are increasingly throbby, geriatric and stubborn.
By the time they get less throbby, they aren’t likely to have much of a pulse. The Party will be Braverman, Patel, Badenoch, Gove, Truss and a whole bunch of Uber-safe seat talentless nobodies. A huge chunk of the already talentless cabinet will be gone. It’s going to take an awfully long time to rebuild. If they split, it’s highly likely the throbbers will be tempted to merge with the likes of Reform and the more centrist ones will have no grassroots, they might as well realign with the LibDems, who ideologically they will be much closer to than the rest of their party.
I really don’t see how the current party actually unites along more “sensible” policy lines.
