I live in the the Far West burbs, which is pretty purple, and I've spent a lot of time in small town Wisconsin for the last 16 years. I talk politics with people in both places regularly. And the answer is yes, the Senator from Illinois is out of touch with Middle America. To them, it's the economy, stupid taken to a whole new level. These people don't have good jobs available to them, they want decent jobs. I've been to plenty of small towns in Wisconsin. I look at what there is to do for work in town. They're lucky if they have a food manufacturing plant in town. Most jobs in those areas are in retail and food service. There really isn't much else. They want upward mobility. The best jobs in a given town used to be public school jobs, but since Scott Walker destroyed the unions there, there really aren't good jobs to be had in small town Wisconsin.
Even in my own life, I'm struggling to get an opportunity to earn a decent wage. I have my own issues, but that shouldn't prevent me from earning a decent living.
Mainstream Dems are deaf to this problem, and until they acknowledge it, they will continue to lose elections.
