Nope, that's more like trumpery. Well-recognized for centuries before the current crop of Trumps was even born:

OTOH "Conservatism" is simply the desire to hold on to, or conserve what there currently is, rather than progress toward something different.
Whether the progress is for the better or worse or even if anybody knows for sure.
Truly the opposite of "progressive". Neither one inherently good or bad.
And as can be seen, an indication of the relative greatness of American leaders who can be judged by their ability to wisely balance the interests of all citizens. The US has a history of exceptional true leaders since the beginning, but not every single one. Some have been far from saintly, and some not even suitable for a free country.
Quite a lot of times neither conservative nor progressive seem like as much of a driving force unless their hallmarks are in decline to the point where some things that were perceived as precious to conserve or progress toward or beyond had already been lost to a certain extent, or otherwise under increased threat.
