To me, on the state & national stage, the democrats widely outplayed the republicans. What did Bill Clinton say? "It's the economy, stupid"! The extended government shutdown, with healthcare costs rapidly increasing, with pricing of all goods also increasing (remember tariffs, just to mention one thing) and so forth, have weighed heavily in the minds of many voters. For some voters, the perceived heavy handedness of the current administration, also energized segments of the democrats.
I do not view Mandami as the shape of things to come. I do view the current results as continuing, if the republicans don't get their own house in order. This country has a widening gap between the lower and upper classes, with the middle disappearing. I cannot fathom how the wealth of billionaires is increasing two and three-fold (For example, look at Mark Cuban, or even at our president and his family bearing in mind I am a republican).
As for our local election, in another thread, I posted "meet the new boss, the same as the old boss". I stand by the post.
