If I am wrong,it just more of the same. Business as usual. But IF I am right,this might end up being something really special. It is already special in the sense that his run for the WH has destroyed the insider good old boy club,where candidates had to kiss the rings of the RNC and the DNC to have any hope at all of winning. That alone is a pretty significant accomplishment.
Being wrong could have some different results.
In his quest for being 'the greatest', he might start breaking rules to impose policy extra-Constitutionally. I want things set right, but have great concern if we end up with two juxtaposed presidents running things like dictators. To say the least, that would be a dangerous precedent and establish a 'fundamental change' that could be the end of any hope to restore the Constitutional Republic.
So I want positive (conservative) change, but within the rules. His ego might lead him to break those rules, and that would be dangerous to all our Liberty in the long run.
He also might underperform in that sense, and do little or nothing but a few 'feelgood' projects that give the illusion of progress back to the Republic, but accomplish little. That would be a wasted opportunity, but little different than the Bush administration in that regard, possibly without engaging in a war or two.
In the worst case scenario, he might whip out some leftist stances which have the full hell-bent vote buying capability that makes them popular among certain very vocal sets and go the wrong way. I would hope anyone in the GOP (and elsewhere) evaluates the policy and doesn't assume the source makes it good, but that is the somnolent pitfall Republicans seem to fall into, the assumption that all is good because 'their guy' is in office. They all demand our scrutiny.
I'm a little suspicious of his 'outsider' status, too. Oh, as a politician, certainly, he hasn't held office himself. That doesn't mean he hasn't played 'kingmaker' a bit, both with contributions and appearances, close enough to the throne to affect it, but not sitting on it. Behind the scenes, that can affect policy, especially those he hobnobs with--and with a high public profile, such hobnobbing would be expected.
But he has apparently shocked the media and the Dems. Perhaps they underestimated the number of people they were pissing off. Even with rampant dislike of Trump within the Republican Party, the exodus of many long term party members, and the negatives he had, the heir apparent to the Obama chair failed to prevail. That refutation, fragmented as it was, in a low turnout year in the General, and with some 10% going to other than GOP or DEM candidates (a rejection of both major candidates), was a clear refutation of both the liberal (leftist) candidates and their policies and actions, as well as the policies they passed, and the claims they had made of success. That alone was good to see.
