A lot of what the President does is ineffectual. And this is speaking with generality, including Presidents Obama, Biden, Clinton, et. al.

The modern method of "ruling by Executive Order/Action" is a clever political ruse. It garners a lot of attention to decree an EO on some wedge issue, doesn't it? It stirs the pot quite effectively, even if the EO isn't, in fact, effective to do anything at all.

Ruling by EO is a way to keep campaign promises. It's a way to assuage constituents and donors and benefactors, "hey, I'm doing what you wanted from me!" and it's a way to keep ahold of the narrative. What it isn't, is effective governance. The USA is not ruled by decree. The EOs, if they are on subjects that are normally the remit of the judicial or legislative branch, may not do much, if anything at all. The President can say he's meddling with the national budget; the media can say he's meddling; the citizens can all complain that he's meddling, but only Congress can actually do budgetary things. The "#nokings" protests are attacking a straw man, because the USA has no king indeed. We uphold the Constitution in this house.

A lot of EOs simply get blocked or countermanded or never take effect, and remain as Presidential Suggestions or Presidential Wishful Thinking entirely. And nobody notices when they fizzle: they only notice when the pen hits paper and they supposedly take effect. They fulfill his promises. They galvanize the base. They assuage benefactors.

Don't be fooled, though. Ruling by EO is simply another layer of lawfare. It's not effective governance and it's not intended to be. It's intended to confuse and beguile you. What is it that Sun Tzu and Saul Alinsky said about having power? Check on that first.

What happens if the president ignores the budget and spends money how he wants?

Interesting. I wonder how those who were laid off by the Government feel about this. Or those who are harmed by ICE Agents. Maybe those who are stuck in limbo because their visas aren’t going to be renewed.

You’re point about /effective/ governance makes sense. To that I agree, often the EOs are overturned or have little affect.

However, the damage EOs cause is very real, lasting, and can be disastrous. For example Trumps tariffs, while ineffective at their (stated) goal, were eventually overturned. But the damage they caused will be very long lasting. Supply chains are organic, they respond to outside forces, when those forces cause them to shift and change. Rarely do they on their own shift back.
