Not much. The generalized suggestions are still good ones: build up and maintain an emergency reserve fund of 6 to 9 months (a combination of an ordinary bank account, SSBs, and OA if you have a mortgage work well), cover genuine insurance necessities, dollar cost average into low cost and well diversified investments, and don't do anything stupid (smoke, drink excessively, etc.)
At the margins you might make some tweaks. For example, maybe you postpone your Disney World vacation until U.S. leadership changes and pick Tokyo Disney instead. I can understand how greater uncertainty might influence highly discretionary decisions at the margins.
A plurality of voting Americans picked Donald Trump, yes. And they should have foreseen this trade war (as a notable example) and understood its ramifications, absolutely. But I don't think it's fair to lean too much into a "blame the voters" mentality. Some of them genuinely believed Donald Trump would keep his promises — and not do things he didn't promise, such as launch a trade war against Canada in flagrant violation of the trade agreement he negotiated and signed. Some of them just got bad information. And lots of non-swing state Harris supporters didn't bother voting since they couldn't realistically decide the election. I don't think that's at all wise, but many would be voters feel that way.
But yeah, elections have consequences. Sometimes gigantic consequences.
