I guess we'll have to disagree on that then. There were promises made...pre-election ones, which Harper reneged on. Williams is simply calling another liar to task. If Harper hadn't made the promise, he should have come out about it when Williams stated a deal and agreement had been reached, prior to the election.
I just don't see him as being on another level at all. He is not saying Newfoundland was raped by the feds, he is saying a major agreement has been blown off by the Prime Minister, one that could give Newfoundland billions in revenue and help ween the province off of equalisation. I never vote Conservative in federal elections anyways as they are a bit too conservative and not at all progressive, but even if I did, I would think twice.
