I'll try again

What was it that he went to the EU hoping to get, and what did he manage to come back with? For you to have determined that it's guff you must have a detailed understanding of both.
google it Bruce it was not much he came back with as it had to be ratified back in the EU after the result which was absurd, to come back with bits and bobs and cost him his job!
I did not take much notice of what he was promised if we remained as i did not like it getting ratified after the referendum as it may have got adjusted or wrote of completely here's a flavour for you-
Cameron found a chilly reception across the Channel to his demands. EU leaders such as Germany’s Angela Merkel wanted to help him make the case to stay in the EU. But they were also distracted by the unprecedentedly large waves of migrants flooding into the Continent and the aftershocks of the Greek debt crisis. The other 27 EU countries were reluctant to create different rules for the U.K. In particular Merkel shot down Cameron’s efforts to carve out a British exception to the EU’s freedom of citizens to work and live anywhere in the bloc.
The prime minister decided to compromise. His advisers were eager to get a deal with Brussels and hold a referendum sooner than later. Delay would in their view carry higher risks. Another year of negative stories about the Continent “would absolutely destroy” his chances of winning a vote, he was told by senior figures in the Remain effort.
As Brussels held its ground, Cameron dropped his manifesto commitment for new EU workers to wait four years before accessing benefits, as long as something was done to cut immigration. In February Britain and the EU struck a deal. Britain would get an “emergency brake,” allowing the U.K. to withhold access to benefits for new migrants for a one-off period of seven years.
“I don’t think we ever thought this was going to be the golden chalice,” a Cameron adviser said, referring to the Obama visit in April.
Cameron thought it was a good deal under the circumstances, one of his advisers said. But the British pressed panned it roundly (“Call that a deal, Dave?” the Daily Mail raged on its front page) and the Out campaigners accused him of a sellout.
