j4u: you are just repeating yourself. 
Based on how the Liberal numbers kept increasing thru the 2015 campaign, I could pontificate that if the election period  had been 1 or 2 weeks longer, then the Liberals would have won by a bigger margin.
But I won't do that. I'll leave idle and pointless speculation to you.
But one thing that isn't speculation, not on my part: Liberal strategists and the general public keep seeing polls showing the Liberals way ahead - there is no way they can be 'concerned' about that, no matter how many times you repeat that they are.
You have an theory in your head. Based on actual facts, it's wrong. Best give it up before it ends in tears.
