I'm not a natural Labour voter, but they have an approximately 25 point lead at the moment - they're very much getting their act together. I'm not sure where the "hating Israel" thing comes from, that talking point is several years out of date now.
They aren't really getting their act together, they aren't doing much different to what they were doing before that poll lead. That lead is the result of the Conservatives having constant leadership turmoil and appointing unpopular people to the Cabinet. It's a consequence of ruling party dysfunction rather than Labour suddenly improving.
