Basically, the only thing the conservatives are offering is the "best Brexit deal" - a statement so vague as to have no substantive content whatsoever, and one which seems pretty unachievable given the team that are likely to be involved in the negotiations. There is literally not one other thing they have said in this election campaign that offers anything good for the country ... unless you happen to already be very rich (as, of course, all of the key players in the last government are). There is no let up to the threat to human rights, education, health, transport, international relationships that we have already seen from the tories. The rest of their campaign has been spent, with the collusion of key sections of the media, trying to say that Corbyn and his team would be bad for the country - as a means of distracting people from the appalling impact that their own manifesto will have.
Despite this, Corbyn has presented himself as measured, thoughtful, polite and a much more convincing figure for PM than May. I have several issues with Labour. One is that their manifesto promises are financially unachievable. Another is that whilst I would be happy to see Corbyn in 10 Downing Street, I don't believe the left wing of the party has the necessary competence to attempt to deliver anything close to what they have been talking about. And the third is that I still have not forgotten what Labour did from 1997-2010 - the misguided foreign adventurism and the laxity regarding the City of London which permitted them to wreck the economy. Note that I don't believe that this was fundamentally Labour's fault - this was the financial hard right wing, a sector of the economy that is happy to bypass political process altogether, and actually deserved the Icelandic solution of failure and prosecution, were that not to have had such an appalling impact on millions of innocent people. But it was on Labour's watch.
The fact that the electorate can apparently forget holds out hope in the long term for the party I still prefer, the Libdems. Some are still punishing them for (in effect) not being the biggest party in the coalition from 2010-2015, despite the fact that they managed to hold back the appalling right wing programme that the tories have since embarked upon. "Liberal" (that is, anti-liberal) secularists worked hard to damage Farron and undermine him from the start of the campaign, which is particularly daft as the libdem agenda is much closer to their mindset and more authentic than either of the two main parties. It was similar to what happened to Orson Scott Card with the film Ender's Game - it had a profound and overt anti-war message, but "liberals" could not see beyond Scott Card's attitude to other issues, so chucked the baby out with the bathwater.
With a big drop in Labour's polling position, and the largest party continuing to oppose Brexit, the Libdems might have hoped to have seen an increase in their share of the vote. This has not happened, and this is also despite their manifesto being generally well regarded and thought of as the most honest and realistic. It's not going to make a difference, and I can't imagine that the Libdems are going to advance significantly, if at all, in this election, but do at least check that you're voting for a party where you believe in the policies, not one that the media are telling you is the best one.
