I live in CT. I would say it is about equal percentages Bernie/Hillary bumper stickers in my area. I suspect Bernie probably has most of his support in VT, MA and RI.
I've seen very few - if any - Hillary signs/stickers in northern CT/ southern MA. But LOTS of Bernie lawn signs.. (barf).
Just saw a Subaru from Vermont with a TRUMP sticker on I-91 in Springfield, MA earlier tonight. That must go over well in the The Socialist Republik of Vermont these days, LOL!
