For sure. But I just don't really see how the answer is splitting into two parties. I just mean to say internal dispute is not like an exclusive Labour thing if the Tories are going through leaders even while in power.
The reality is unfortunately this is a country that mostly votes the Tories in, occasionally the other party. Can't really see how if you split the other party up that mostly doesn't just become always.
The Tories faced the same problem in the 2000s that Labour now faces. Their base did not reflect the national vote. The famous speech from Theresa May was the first step towards realigning. The problem with Labour, that the Tories did not have, is that the base sees itself as in the right on all matters, and will not realign. And unlike the Tories, the Labour base would rather the opponents stay in national power than adjust.
May's speech happened 5 years into the Labour government, under Ian Duncan Smith. 11 years into the Tory government, and the Labour base still has no intention of realigning, but is still pushing to frame the argument on the left to suit itself rather than the country.
