He didn't campaign strongly because he's been consistently opposed to European integration for most of his parliamentary career. He believes it has a hugely negative effect on job prospects and wages for the poorest in society.
The only reason he even vaguely put his support behind remain was so that he wouldn't face a rebellion among his MPs. I'm pretty certain if he was still a backbencher he would have supported leaving.

It's rare that it is so out in the open but the vast majority of decisions are made like this.

He was out campaigning for a Remain vote but this was largely ignored by the media.
I was pretty happy with Corbyn so far but his complete lack of doing anything throughout this campaign is embarrassing. I'm guessing he didn't want to lose working-class votes but that makes him as bad as Boris Johnson. Deciding the fate of the country base don what's best for his political career.
