As I've said, I don't expect this "honeymoon period" to last. Corbyn's real hope was defeating the QS, and that failed. Now he'll be left sniping at the sidelines and, provided the Tories play things safe, which is likely due to Brexit going on, his and his disciples continually sniping about "Evil Tories", "austerity", "rights", etc, whilst not being able to show, in the most minimal of ways, how their plans are actually feasible will turn people against them.
There's already "comments" appearing elsewhere over the nonsense being spouted by the Left over Grenfell, and how that nonsense has subsided since the likes of the tale behind Camden, a Labour council, and what looks like their "errors", is also being noticed and does point things away from the Tories in this respect.
So as time goes on, provided the Tories do keep a lid on things, the headlines for Labour will worsen and that has already been seen thanks to Chukka's ill-fated amendment and the matter of 49 Labour MP's voting against Jeremy's orders. It's not the Tories that are seen as being "divided", it's Labour and that sort of attention is likely to only increase and will likely be detrimental. You just have to see the reports of what Field-Commodore Nugget has said regarding Chukka's amendment to see how much that rift exists, and every single thing like that will now be reported no matter how small it is.
Don't get me wrong, there's no question the Tories howled it with their manifesto which could have been much, much, better written. They were complacent and I doubt they would make the same mistake in a hurry, and should Labour continue on the same "Student Union" style of politics then they will turn people off them.
