Stupid polling question

[Alcon]

So, I've anecdotally observed that polls tend to under-estimate the margins in landslide races a lot of the time.  Is this true, and is there any explanation of this phenomenon?

I think we also tend to ignore polls that show outrageous margins that we cannot believe.  Pollsters also do not want to look foolish, I would assume, and release droves of ridiculous numbers.  However, I may be completely wrong

Yes, but it tends not to occur is Presidential races.  Wonder why...

Do we have any polls from '84, '72, and '64?

We do from '88 and '96, and my comment is correct there.  The polls were directly on in 1984, iirc.  Don't remember 1964 or 1972, actually, though there would be much fewer polls then than now.
