The MSM and Dems are using the polls for cover.
If Obama wins, the polls showing Obama even or ahead were correct and the supposed oversampling of Dems becomes irrelevant.
If Romney wins, shock and surprise, a shellacking (remember 2010?), where did Team Obama go wrong? Recounts. The election was fixed, rigged. Too many dead Republicans voted. Dems were intimidated and kept away from the ballot boxes. Wahhhhhh, Waaaaaaaahhhh
[The purpose of the oversampling is a propagandist attempt to sway voters toward the ‘winning’ candidate bandwagon.]

Two decades ago, when I didn’t have cable, I noticed the network news programs frequently headlined polls (that they commissioned) as one of the major news stories. Slow news day? Commission a poll. So what if poll content can be written in such a manner that produces a desired result.
If Romney-Ryan do win in a landslide of Reagan proportions, it could very well signify that MSM have lost much of their influence on the general public.
The MSM are using the polls to discourage Romney voters and help the Dems raise money and inhibit GOP fund raising efforts. Contributors want to back a winner. They don’t want to send money to a sure loser.
