IMO Trumps base is even more energized than ever and people will vote to empower him even if that means crossing their typical party lines.
Small sample size but my circle of friends was a mixed bag before the election and now nearly all support Trumps performance even they don’t agree with how he handles himself sometimes. What @bing stated resonates through my circle of friends. Watching my paycheck get bigger and my retirement money grow trumps all else.
As far as signs pointing to anything I think the problem with polls is that they are inherently flawed. Beliefs and convictions make some groups more likely to want to participate in them than others, skewing actual results. That’s why Trump winning was such a surprise. Media though they were getting a good sample of what the american population was going to do without considering that someone like myself is never going to answer a survey or poll.
