Well run polls take a random sample from a properly stratified population.

The questions in polls vs betting are different. One asks who you want to win, the other who you think will win.

Those who bet are not a random sample. They tend to have certain demographic characteristics, mainly being male.

Yet some studies have shown the betting markets are more accurate. Guess we'll find out in November.
