Glad you enjoyed it. Just answering kind with kind, since polls were your criteria. As far as the reliability of polls, you might want to read "Mobocracy" by Matthew Robinson (a conservative, BTW). Polls have degenerated into not much more than propaganda tools (9 out of 10 people can't be wrong!) used more to sway public opinion than to report on it, and the RNC is not immune.
Of course, one must look at the wording of questions used in polls. But polls, whatever their ultimate use, are scientifically reflective of whatever they are trying to measure.
I am speaking, of course, of polls done by professional polling firms, and not the idiotic internet variety which are basically used as a vehicle for web hits.
