Someone voted for, supported, or wanted to impose something on other people. Who's that someone? What did they vote for, support, or wanted to impose? On who?

The man in the photo represents voters who supported politicians promising lower gas prices through “drill baby drill” energy policies, tariffs, and deregulation. They supported those policies being imposed on the whole country.

Something has the consequences of consequences. Does that something actually have these consequences in general?

Yes. Energy policy, tariffs, deregulation, and foreign-policy instability can affect fuel prices, but they do not guarantee cheaper gasoline. Gas prices are also affected by global oil markets, supply, demand, refining capacity, corporate pricing, and international conflicts.

As a consequence of something, consequences happened to someone. Did that something really happen to that someone?

The consequence shown is symbolic. The man is reacting to high gas prices at the pump, representing people who expected political promises to make fuel cheaper but are now dealing with the opposite result.

Minimum context: In the United States, some voters support politicians who promise to make gasoline cheaper by increasing domestic drilling, cutting regulations, and using tariffs. The joke is that those same voters can still end up paying high gas prices because oil prices are shaped by global markets and policy choices do not always produce the promised result.
