I still think the bigger “tell” is the “signals intelligence”...what are you seeing and hearing from those around you.
I live and work in deep blue country, and while I’ve seen a handful of Clinton bumper stickers, I’ve seen more residual Bernie ones, and in terms of Clinton lawn signs I’ve seen exactly three. For a region and people big on “virtue signalling” (Starbucks, NPR, Whole Foods, etc.), I think that says something.
I live in ‘nice white liberal’ central here in St. Louis, or at least I was crashing in this area during election season. In 2008 I saw no end of Obama signs. In 2012 I saw fewer but still enough Obama signs.
Now in 2016, I have yet to see a single Hillary sign OR bumper sticker. I’ve seen a single Bernie sticker, but nothing else at all.
