Yeah, betting lines as predictors are interesting, and can be useful, but as you've pointed out, it's important to understand how betting lines are set-- essentially it's another form of polling. Similar to polling, sample size is important, and also controlling for who chooses to participate. For example, I have a hunch that bettors skew to Trump supporters.
