I just got a leaflet through the door from the Scottish Conservatives. I should add my political leanings mean I would never vote for them, so this may have clouded my view
Part of the leaflet gives statistics from a poll published in September (the date is shown clearly so no problems there) showing the Conservatives with 52% of the electorate behind them, labour with 24% and the SNP with 12%. The byline is ONLY A VOTE FOR THE SCOTTISH CONSERVATIVES CAN KEEP LABOUR OUT OF POWER AT WESTMINSTER.
I guess their idea is that the SNP had been getting more popular in Scotland and that it was a choice for voters who had been disillusioned with Labour. What they want to do is convince people that a vote for the SNP is a wasted vote if they're trying to oust Labour.
The problem is I have just looked up the poll and it's a UK-wide poll of just over 1000 people.
Of course the bloomin' SNP are hardly going to have any support over a nationwide poll, Scottish people only make up about 10% of the UK's population!
In essence a nationwide poll is not useful for a Scottish person in deciding how to vote in their constituency and I think it is misleading.
I'm not affiliated with any particular party by the way and after reading back through this think maybe I need to get out more....
