I would wager that almost all of rural America refrains from sharing their political beliefs, except for in their towns. You won't see very many Farmers tweeting. The construction sector is the same. Even in the union side of things, you'll find a lot of conservatives. But I don't see how any construction related persons could vote Dem, it's just not their thing. If you think grab her by the pussy is bad, you've never been on a construction site.
