Is this supposed to be about judging whether or not Trump is seen as a successful President?
That’s always more of a politicking question than a factual one, especially during the Presidency.
I don’t know about Trump being all that “brilliant,” myself. So far, his actions during the voting season and after both, have more of the look of “try whatever seems fun at the time” than it does of crafty strategy.
We are in a very different kind of time now than the US has ever been through before, for a lot of different reasons, and I think Trump’s victory at the polls reflects that. The Republican Party has never been this oriented towards deception before; the Democrats have been as disorganized, but never had such a dearth of people at the top who had a clue, before; the relative stability of the world that began after World War Two, has been completely shattered; the US has never been seriously challenged economically by another single country in modern times.
The Republican’s titular leader, Trump, NEVER had the full support of “his” own party, with strong opposition from within remaining high, right through the election. Remember, 100% of Trump’s efforts to lead so far, have NOT involved a unified, energetic action of the Republican controlled Congress. No spending bills have even been introduced to support Trumps agendas, and the Republicans aren’t doing any visible work, even to get the ACA reversed.
Trumps successes so far, are political, and only favor his support from his fans. He still behaves as though he is an outsider criticizing the government, instead of the leader of it.
And then there's the Agenda items. A President can succeed in getting his agenda items through and done, but still be seen as having failed, if the agenda items end up being problematic. Bush seemed to "win" the wars he got us in to, but the fact that those "wins" didn't accomplish an end to the dangers we were facing (more like a seeming increase), achieving those goals led to a Democratic victory. Bush got his radical tax cuts, but they didn't fix anything in the economy, which proceeded to come to near complete collapse. Obama "succeeded" in getting the ACA passed, but only in a messed up condition, and it turned into a relative debacle for him and for the Democrats despite the fact that they "won" that item.
If Trump builds his wall, ostentatiously ejects a lot of illegals, upends all the international trade agreements, and gets other governments to take over the military defense that the US has led since WW2, that will go down as a successful series of AGENDA items, but unless the RESULTS make most Americans think well of them, they wont go down as successes. If the decline in the American middle class continues, if wages remain flat, and if medical costs remain problematic, Trump wont be seen to have succeeded whether he gets his to-do list completed or not.
