Re: local councils, I think part of the problem is that the general view is that they're basically responsible for bins and parks and that's it. I don't know if it's an educational campaign that's required or whether, were they given further powers people might be more interested in it, but I don't think councils being shit are an inherent flaw in the idea of "localism".
The way some people talk is like Corbyn is some sort of dictator who somehow got control of the party. Corbyn was democratically elected as leader using the system set in place and agreed by the party.
Corbyn was unelectable as leader until he was elected as leader. Then people decided he is unelectable as prime minister 5 years before the general election.
How are these people judging the political landscape of the next 5 years and where were they when the last two labour governments failed miserably? The last labour leader in particular was polling highly throughout his whole term but still managed to actually do worse than the previous leader.
Regardless of whether people feel he is unelectable, it is disgusting to see people look down on passionate Corbyn supporters. Some people feel passionately about voting for something they believe in. Other people take a more tactical approach to democracy. Both are valid and the result should always be respected.
Whenever you're talking about predicting elections - or, rather, deciding if something's
possible - there's basically just one question you need to ask. "Where will the votes come from?" That's really it. If you can answer that, if you can see a pathway to victory then at least it's possible, and it gives you some idea on the type of platform to pursue.
Corbyn winning the leadership was not predicted at the beginning, but by the time of the election it was clear that there was a groundswell of support behind him. But this was always possible. You only need to look to the US primary system to see that, when the party is given greater control to pick a candidate, they almost always end up being more to the left or to the right of the party's platform (depending on which way it leans), because the
membership is too. Tory members are too. The difference with that election was that it was the first major leadership election which had a significant element of involvement from the party membership. So of course you could see a route for how someone like Corbyn could win, and this was the first election of a leader in which something like this
could happen, so naturally it also has no precedent.
If we apply that the general election, though, it's basically impossible to see a route to power. In 2015 we'd had, in theory, 5 years of "ConDem" cuts and austerity. Doctors were angry, teachers we angry (when aren't they though, tbf?), UKIP was polling high and when people were presented with Ed Miliband as the alternative they said "Hmm, no, I'd rather have more Tories please". If people though Ed was a bit weird and not-very statesmanlike, what do you imagine they feel about Jezza? So Ed was either too left wing for people, or he wasn't left wing enough. But that latter one obviously makes no sense if people chose the Tories instead. What this basically leaves you with, as a "route",is two options; One is people who didn't vote at all now being energised. To some extent that's what we have seen with his leadership election, but not in anything like sufficient numbers, and it's often within areas where Labour is already going to win anyway. There's no point getting another 10,000 excited hipsters in Tower Hamlets to vote for you when Ali holds Bethnal Green with a 24,000 vote majority. There's evidence to suggest that non-voters don't have leanings that vary massively from the wider population, so there's no reason to think that a high turnout would break for Corbyn anyway.
The second route is to move to the right. This is effectively what Blair did when he ripped up Clause 4 on stage. The obvious benefit of this route is that - unlike trying to gain votes from the left - every vote you gain from the right is a vote you're
taking away from the Tories, so it doubles up. Not only that, but UKIP* and the Tory vote shares demonstrates that half the country leans that way, so you know there are votes there to gain. This isn't always the case on the left, where you have parties like the SNP who are really no more or less left than Labour but have a hugely important USP that Labour simply can't reproduce. Finally, who are Labour's main marginal battle grounds with? Tories and Lib Dems (who, whilst they've been fucked in many ways, still have a strong ground game and are popular enough in certain areas that they can split the vote even if they can't win). Both of these parties are to the right of Labour, so if they're trying to beat these parties, moving
further away is only going to alienate them. Sure, moving to the right will make taking Brighton off the Greens a little harder, but moving to the left makes taking
all the others harder, except in Scotland but they're fucked there anyway until the independence issue is settled one way or the other.
* I know UKIP doesn't only attract people from the right, and it certainly does take a lot of Labour voters, but those voters are unlikely to be primarily motivated by economic policy, so the left-right alignment of the party trying to win them isn't really as important as the other axis.
So, yeah, basically, where will these votes come from under Corbyn? There aren't many votes on the left and he won't go to the right.
Re: your last paragraph, I think you can split Corbyn voters into two core groups; People who like him and think he can win, and people who like him, think he can't win but will vote for him anyway because they like him. The former group are, I think, incredibly, incredibly optimistic to the point of at least a mild detachment from reality, but they're at least earnest and you can honestly say they have the countries best interest in mind. But the people who support him despite knowing he can't win - what's their excuse? Why would they possibly support a candidate when they know he will make the opposition's chance of winning higher rather than lower? and with greater seats comes greater ability to run amok. With a PLP that clearly hates him, he can't generate a proper opposition but these people would actively prolong that, removing even more barriers from the Government.
Not only that, but on a meta-level, if he suffers a loss he'll become the "Michael Foot" of our generation - a loony lefty proving once against that the left can't win elections, that they're a laughing stock and that the only reasonable parties are those on the right. It took John Smith and Tony Blair to do what they did to "detoxify" the Labour brand, just like it too Cameron to detoxify the Tories. But you'll notice that both of those processes ocurred during lengthy, lengthy periods in opposition. By supporting him, you could - ironically - be doing the ideas you want to be implemented be dealt fatal blows for an entire generation. There'll be a resulting purge of the left within the party (just like the Blairites were purged) and you will draw significant power out of the left wing of the PLP, leaving more of the right.
Political parties aren't football teams, there's no glory in losing. If the people don't vote for you to do things, you can't do things, and the other guys can. It's really that simple. So if you do think Corbyn can win and you want to support him and his policies, voting for him is undoubtedly the right thing to do. If you like him and his ideas are great but you don't think he can win, you have an obligation, IMO, to vote for Smith if you actually care about people's lives being improved, because there's
no version of a Corbyn future where that happens (unless you're a Tory).
