YOU made the claim! Hence you backup your claim with facts or hang it up. Fact is you can't find any data to support your claim. Given that my link above shows Gallup polls repeatedly ripping the democrats a new one on the political demographics of this nation, your claim about Gallup supporting the dems with skewed data/methodologies rings hollow.
Let me know when you'd like to discuss this using facts vs rumor?
I was "push polled" by Gallup, and gave you a specific example with exact quotes of what occurred up-thread.....personal experience........If you choose to ignore it, that is your option.
I too have a great deal of experience evaluating polls, as well as statistical analysis in general......the suggestion was made that you might read some other threads where this has been extensively discussed in the past on this board......it would save you some embarrassment, as well as saving the rest of us time.
Typically it is good board etiquette to spend some time reading, and evaluating discussions that have been ongoing before on a specific topic, when you are new to a forum, rather than barging in and making an ass of yourself before you have accumulated a dozen posts.
All here are welcome, and the mods are pretty lenient, but it is always wise to get to know the folks before challenging them, as most of us have been here since the board was founded, and migrated here from another particular forum prior to that......just saying......therefore a lot of these discussions are "old hat" to an extent.
