I'd be cautious about reading too much into this.
Whilst the Conservatives have not had a good couple of weeks, when it comes to the privacy of the polling booth, I suspect many floating voters will end up choosing the familiar option of May and the Conservatives rather than taking a risk on voting Corbyn.
I have a suspicion the result may well not actually be massively different from today's disposition, but we'll see. I don't think May has presented herself and party very well in the last couple of weeks, but the question is will large numbers of people think Corbyn is a better option? A few more Diane Abbott interview fiascos may put the momentum back with the Conservatives of course.
People - their core voters, will want to know if they won't be getting their winter fuel allowance and will want to know if granny's house is to be handed over to the council.
Saying the Conservatives have "not had a good couple of weeks" is a bit of an understatement..they had a lead where they could have forced Labour to bat again and still win by an innings, and it's vastly reduced and could have gone by then next poll.
They called the election because they were SO SURE of winning, without real policies (as evidence, m'lud, why keep rabbiting on about "weak and wobb...sorry, strong and whatever") and now they and she have been found out.
So the public - their voters - are now asking where the "cut" is. Who will miss the fuel allowance.
No answer = they all will think it's them that will suffer.
An answer = those worse off may not vote for them.
Corbyn must be in dreamland, leading a party that doesn't want him to at least a moral victory.
And there's me thinking this was a dull, pointless election that I couldn't be bothered with....
It's worth reading the comments on the Daily Mayl's website; sure some socialists may be in there and trolling, but by-and-large (and I've checked) there's a load of people that have spent years writing they hate foreigners, hate the EU, hate socialism, hate anything red, blah blah blah who have now turned against May. They don't trust her to buy a loaf of bread, let alone negotiate the EU. Go see!
