Possibly a bounce from the State of the Union speech. The President stuck largely to platitudes and was better at veiling his right-wing agenda. He could of course point to greater enthusiasm by the Master Class in the economy (remember, in Trump's America, you know who matters and you know who doesn't). He was careful to even make a veiled attack on abortion by calling attention to a child adopted instead of aborted... anecdotal stuff, the usual fare of right-wingers about the effects of their ideology upon classes of people usually their victims.
I noticed that of people watching the speech, approval was high -- probably because Democrats were not watching it as readily as they would have watched an Obama speech.
About everyone to the left of the absolute center in American politics has long given up on this President. Watch for statewide polls. Donald Trump is not the Great Communicator that Ronald Reagan was.
Of course, should statewide polls start showing a move toward Trump and the GOP, then we might expect the Democratic edge in Congressional polling to completely disappear and several incumbent Senate Democrats not only in Indiana, Missouri, Montana, and North Dakota -- but also in Florida, Ohio, Pennsylvania, Wisconsin, Michigan, and Minnesota. You can also expect that Donald Trump will win in a landslide and supermajorities in both Houses of Congress and most state legislatures will be able to turn America into a dominant-party system in which the Republican Party is the defined "leading force" in politics.
If you don't think it possible...the 1936 (Stalin) Constitution of the Soviet Union was to a large part a plagiarism of ours. It simply had a few subtle tweaks.
...and the cops can pull my dead body out of my repossessed house. In that sort of America, the only virtue is wealth and what it can buy, and most people will be consigned to roles as desititute toilers, paid too little but facing monopoly prices, and getting to see even children's educated gutted because there will be a need for children in the mines digging out President Trump's 'beautiful clean coal'. Government will exist to punish anyone not in groups deemed to be true believers in the Union of Christian and Corporate States.
(I suppose I have the backstory for a dystopian science fiction novel. May this all be wrong!)
Have you ever read the Handmaiden's Tale?
