2016 happened because decent people don't join political parties, leaving the business of Government to socially inadequate, physically repellent gits with an axe to grind*. In normal circumstances, this makes politics easier for genuinely impressive people to progress through the flotsam of monomaniacs. To be a Grown-up in the Tory Party 1997-2010 was to be able to consider an issue beyond the EU. For Labour it's all about not dreaming of Strike Action by "the workers". Thus the Liberal Centre consolidated a hold on the country, but became complacent to the poison seeping into parties even as the Smug centrist consensus made everyone fat and rich.
There has been a steady, and persistent hollowing out of the political parties. Labour used to be allied to a Trades Union movement that delivered services - health insurance, education and so forth to its members. The Trades Unions of Pre-War Britain where an overwhelming force for good. Atlee's welfare state nationalised all the good the Trades Unions used to do, and so corrupted both the principle of welfare (now far, far from Beveridge's original vision of low, universal payments like Child benefit, topped up with contributory elements) and the Trades unions which became a mere tub-thumper for more state spending. This left the Labour party with the sole purpose of defending a welfare settlement that is not under threat, and a Trades Union movement whose purpose had been nationalised so simply became resistant to all and any reform which might make the system as is function better; unions a mere vested interest of public-sector workers. This isn't a place where people capable of holding more than one idea at a time feel comfortable, and so the Labour party was colonised by people who think not shaving is a political act.
This malodorous and poorly groomed cancer has destroyed the Labour party. It's over, there's no point being in Labour unless you're a Identity politics obsessed Corbynite who laments the end of the Soviet Union.
The Tories at least had the sense to try to vomit the most toxic of their nutters into a bucket marked UKIP, a bucket the dog is unfortunately returning to. The Conservative party my Grandfather joined (from CPGB, as it happens, Labour even back then were cliquey dick-heads) used to be a forum for the upper middle class (and anyone who aspired to join them) to meet, mate and do business. But the horrible young Tories of the '80s, and the Euro-nutters of the '90s meant that by 1997, the Tories were only really suitable for people who were prepared to discuss "Europe" endlessly in ever-more foaming tones, persuading themselves that the EU is a historic enemy like Napoleon, the Kaisar, Hitler or the USSR. To their credit, the Tory Leadership has long known what to do. All David Cameron ever asked of his party was to "stop banging on about Europe". They couldn't stop picking at the scab, and the result is a catastrophe that has already crashed the Pound, weakened the UK (perhaps fatally) and may yet cause a political crisis in Europe and embolden Putin to start rebuilding the USSR.
The more say over policy and leadership given to the membership, the more the membership has dwindled (unless, like Labour, the membership criteria are designed to invite entryism for the purposes of choosing a leader - by people who've been quietly loyal to the Bennite project for decades). Giving members a say in who leads the party is absurd. Who the prime minister is, should be a matter for MPs, and MPs alone. It is they who must give the Prime Minister a majority and internal party democracy risks, well, exactly what has happened to Labour.
However, that Rubicon has been crossed. Party members now expect a vote on the Leader. The question is what to do about this, and the answer is to choose to be a member of a party at all times, hold your nose if necessary. Do NOT identify with the party, but consider which is best placed to advance your objectives. At the moment, the foul bigots, monomaniacs and morons of UKIP are being re-absorbed from a position where they can do little harm beyond foaming at the mouth and masturbating to Daily Express editorials, to one where they can choose the next prime minister, and Mrs May isn't a healthy specimen. The ex-'KIPpers chance may come to choose their PM sooner than expected.
I'm often asked "How come you're still a Tory?"
Were the Liberal Democrats stronger, I'd be considering them, but I don't trust them on electoral reform (about which they're as silly as Tories are about Europe). But as the Lib-Dems are so far from power, I don't see the tactical benefit of leaving the Tories in a huff, and I broadly agree with the Tories on everything except Brexit. What I'm worried about is the 'KIPpers who're returning to the fold. Unless you want a foul, divisive and ignorant Brexit headbanger to replace May in 2023 or so (Gove for example), Join the Tories, because thanks to Labour's meltdown, Tories and Tories alone will choose the next PM. All not joining a party does is strengthen those (*we) weirdos who still do. Labour moderates, disgusted by Corbyn should cross the floor to the Tories or Liberal democrats, instead of flouncing off to the V&A and opening the way for UKIPish Brexit-o-twats to fight and win a by-elections under Tory colours. Were Tristram hunt now a Tory, not only we could soften this brexit idiocy but also signal just how broad a church the Tories are. 40% of Tory members voted Remain. The tribe that needs to understand the value of a bit of entryism is the liberal centre, who need to abandon any loyalty to their Parties and go to where the power is. The Liberal Centre is complacent because they have for so long occupied the ground sought by all parties, they've not really had to compromise.
At the moment the business of Government is, and will be for the foreseeable future, a Tory-only affair. That need not look like Nigel Farage, but it will, if Remainers abandon the Tories entirely.
