Manipulating party weighting to bias polls?

I disagree with CBS News because of how it weights its respondent pool. And lately, what I have seen is a trend, verging on the ridiculous, of far too many Democrats in the pool to make any sense at all. This has been happening in both national polls and in state polls. For national polls, I mentioned some weeks back how Gallup managed to show Obama declining or staying steady in every political affiliation group over a week while McCain was steady or gained in every such group, yet Gallup’s headline claimed Obama was gaining support overall, a mathematical impossibility without manipulating the proportionate weights.
