I definitely agree with you on that. Yard signs aren’t a scientific polling of balanced demographics. The one caveat I’d throw in there is that I went through the richest neighborhoods (Indian Hills, Cincinnati), and the poorest (Adams County). The absence of Clinton signs is striking.
If there’s no intensity at all across a range of neighborhoods for Clinton, then that doesn’t speak well for the vigor of her supporters. Maybe they’re all out having coughing fits.
Never mind the yard signs. The Washington Post came out this morning with a 50 state poll that, they contend, puts the lid on Trumps campaign. Hillary is so far ahead the contest is over.
Agreed - poor intensity can definitely indicate a lack of motivation to get out and vote for someone.
