However, when it plays out in the mind of a republican, this thinking usually turns into those "many" administrations you mentioned as being all of the liberal ones, and the opposite would be true for a democrat who abides by this mentality. So this person who is sometimes skeptical of the numbers can just turn out to be a partisan that trusts or distrusts the numbers whenever it makes their party look good. I find that to be the case most of the time, but there are always exceptions.
Since the day, as a teenager, I realized how the stats we gathered and measured I have never placed any faith in their accuracy no matter which party was in power. they may reflect a trend and be a small corner of the whole picture, But, IMO less than a 1.5% change is "withing the margin of manipulation", even of the incomplete picture they represent.
