All you have to do is google "Rassmussen Republican Bias." There's a wealth of hard evidence to prove the points. Also plenty of infomation about Scotty Rassmussen taking money from the Bush Campaign, the RNC, several local Republican organizations, a cruise from a conservative think tank, etc.
Scotty has jumped the shark and his business plan is now clearly to pander to conservative clients. It's very well known throughout the professional polling community and the numbers all back it up.
The only people who pay any attention to Rassmussen anymore, are the people who are grinding the same ax that Scotty is grinding. Professional independent polling organizations just don't do that kinda crap.
When did I ever say that Rasmussen has no house bias?
ALL pollsters have a house bias. That's why it's called a "
house bias". It's the bias specific to their "
house". Good shooting Christ. The problem is that you and NYC are so busy going nutso over Rasmussen's bias yet you clearly don't seem to mind anyone else's bias that favors Obama. I don't see you raising much hell that PPP, who is affiliated with the Democratic party, has been releasing polls over the last two months that on average give Obama a five point better spread than the rest of the professional pollsters, yet when they release a poll commissioned by the Daily Kos it's right in line with everyone else. How amazing!! Well where's your outrage over
that bullshit.
This is why when you look at polls you
NEVER take one poll as gospel and by the same token you
NEVER disregard any poll. The house biases, that
every pollster will have, will equal each other out or at least be minimized when you calculate the mean.
Furthermore, the 3.9 bias, you so adamantly insist is accurate yet refuse to provide any documentation for, is ******* laughable. A) the house bias will change from year to year or even month to month. It will also
appear to be greater at certain times of the year when a greater number of RV polls are being performed as opposed to the LV polls that Rasmussen performs exclusively. So right now, when the vast majority of polls are RV polls that have a natural lean toward Democrats, the Rasmussen house bias will appear to be larger although in reality that increase is simply reflecting the natural difference between an RV and LV poll. When the election gets closer everyone will start doing LV polls instead as they are more accurate and then you will see Rasmussen's differential against the mean decrease.
Rightwinger said in an earlier post that Rasmussen's doesn't release their accurate polls until right before the election.
No it just appears that way because right before the election everyone will go from RV to LV and as a result everyone else's polls will suddenly start showing a better Republican performance because they will be eliminating the natural Democratic lean of an RV poll.
B) You clearly are not getting the idea that the more polls an agency does the greater their differential will be. This has
nothing to do with the quality of the pollster and
everything to do with the law of probabilities. The big error that people make is to look at a poll and assume: "
this is what this pollster says IS happening".
Wrong...it's based on a confidence interval that is almost universally set at 95% (though I have caught some unscrupulous pollsters set it lower...and no Rasmussen isn't one of them). What this means is that the poll is saying "
there is a 95% chance that this is what is happening".
Sometimes, the results fall into that 5% and that's what we call an
outlier. Well when you do 9 polls the chances that one of them will be an outlier is low. With only 9 polls
maybe one of them will be an outlier but statistically speaking probably not. When you do hundreds of polls as Rasmussen does, your chances of getting an outlier increases dramatically. With 100 polls, statistically speaking, you can
expect 5 of them to be outliers at least. That's simply the law of probabilities and when factored into the overall differential as an average, it means that differential is going to increase.
So to summarize:
1) Your outrage over house bias is conveniently selective and flat out hypocritical. When you start showing the same outrage over PPP as you are about Rasmussen, I might start taking you more seriously.
2) House bias will change from year to year, month to month, and will be impacted by the type of poll you are doing compared to what type of polls everyone else is doing.
3) You conveniently overlook that polling is subject to laws of randomness and probability. Those laws indicate that the more polls you perform, the more your likelihood of getting an outlier, and hence the more your average differential will increase.
This is basic ******* statistics man....I mean we're talking first semester concepts here and you
still can't seem to grasp it.
