I believe we will. Crane Brinton, Harvard historian published a widely read book that is still popular today, "The Anatomy of Revolution" in which he studied four prominent revolutions - 1640s English, French, American, Russian. Some pundits dispute his basic claim that is can't happen here. I tend to agree only because you need concentrated power in one relatively small geographic territory to really control revolutionary power. That would be very difficult in America. The current GOP majority is out of touch with the rest of the country. Are Los Angeles and New York going to goose-step with a Radical Right Senate? The US Military will not turn on its own people, there would be severe division in military ranks if they tried. The solid economy is popularly attributed to Obama. Weak-minded Americans are not looking for a Nationalist Savior to improve their prospects, they are looking for sound tweaks to economic fairness. Most of all they just want that Orange Menace out of office.
Democrats will do fine on Nov 6 if we capture the House, or even make it 5 seat close (because Main Street Republicans in pink districts will see the writing on the wall), and if we take a few governors' races, and grab state legislative seats by the dozens. We are poised for change, and elections are how the Founders divided power for generational renewal and revolution by voting.
If all that goes against us, we are in deep water and must hunker down. But a lot must go wrong for that to happen.
