I agree that Parliament has caused a Brexit logjam and to be fair both sides of the debate have done that, but you have to ask yourself why ?
Frumpety, I agree a GE should not be a single issue. Jo Swinson has made it one by forming the Remainer Alliance - you will see further upthread that I pointed out that by depriving Remain voters in the target constituencies of a choice (mine is on that list), she is forcing them to sacrifice other legitimate concerns. It's particularly pernicious for Welsh voters who may be pro-Union Remainers because they can't express that view when the only real Remainer choice they are being given is Plaid Cymru. I think her strategy is divisive - I think it's certainly fragmenting the Remainer vote - and it is arguably undemocratic.
I also ask myself why - if MPs are so much better informed than us - they offered us a referendum in the first place, voted overwhelmingly in favour of offering it, voted overwhelmingly in favour of triggering Article 50. Why did both Conservative and Labour Party manifestos in 2017 specifically say they would honour the referendum result?
FWIW, I think some MPs are generally well informed, some are well informed in just a couple of subjects and some are too busy feathering their own nests to worry their heads about what they think, never mind what their constituents think.
I'm also aware of the Burkean view of representative democracy but Burke didn't allow for a direct question to be handed over to the electorate as a binary choice. Neither, it seems, did our own MPs. They are really not a uniformly first class bunch so I am not about to take everything they say as gospel.
