The elephant in the room?

Considering this election was supposed to be all about Brexit, I am amazed at how little is being said about it.  It seems to have degenerated very quickly into a "May keeps U-turning and can't be trusted" versus "Corbyn doesn't believe in Trident and won't protect us" argument.  As far as I can see, the general populous are not that concerned about the forthcoming Brexit negotiations - which of course raises the question - why are we having this election?  Are we all getting our knickers in a twist for no good reason?
