102. You seem to have no idea how polls are weighted. Let me try to explain.
When they get raw data, it may be misbalanced. Too many males, or too many young people, or too many whites, or Latinos, etc etc etc. In order to make sure that the sample is close to being "representative", the sample is reweighted. What that means is that some variables (such as Gender, or Ethnicity or Age) are adjusted to confirm to known, correctly representative weights. Those are the weights that we are talking about.

When you do that, other, secondary variables, that were NOT used as weights and that are NOT known (such as "whom did you vote for") are weighted and changed.

What YOU are claiming is that the "43/37 whom did you vote for in 2000" variable was used as a weight. That is absurd, since it is an unreliable result. People do not lie about their gender, so that can be used as a weight, if you know what the representative sample should contain. People regularly lie about whom they voted for in the past.
