As in astrology, so in polls and politics. One would think that counting votes would be a simple matter. 1,000 votes for candidate A, 2,000 for candidate B, 3,000 for candidate C. But no, political pollsters and pundits then segregate voters and their mode of voting in various ways. Male/female, blue collar male/"educated" male (- cheek!! Why are blue collar people considered uneducated?) White males/black males. White "educated"/white blue collar. Black "educated"/ black blue collar. Same for Hispanic male/female, and for all females. Age groups: under 25, over 40, over 50, over 60, and on... along with any possible permutation of all of the above factors. Religion also has to be added to these exercises in the USA: Roman Catholic, Baptist, Evangelist, Black Churches, and other denominations. They don't bother categorising votes of atheists and agnostics.
Will there ever come a time, in the USA, when most of that categorising will no longer be useful, when the "melting pot" this nation was always trumpeted (small 't'!) to be will truly have completed the envisioned fusion?

Vote Canada for President!
