Very true for Britain as well the Conservatives believe in the secrecy of the ballot box whilst the left love to brag.
One reason I rarely take polls seriously and why the left is always over sampled (apart from partisan bias) is because the conservatives/right wing voters rarely wish to participate keeping their views to themselves.
Good morning - well afternoon for you the Snugs. I'm at work today, so can't watch the Sunday shows. That may be a good thing for my blood pressure, as I tend to scream at the TV.
Another reason the exit polls are wrong, is that many Conservatives here tend to vote absentee, because we DO have JOBS. The working libs take off to vote, and stand in the long lines.
