ELI5: Why doesn't the US lift the Embargo on Cuba?

What benefit does it possibly give now? Back when our relations with Cuba were tense, wasn't it implemented as a sort of show of power? Why not retract it now?

It just seems silly that Americans can't buy Cuban products or travel to Cuba (technically they can, but they can't because they aren't allowed to pay airplane taxes to Cuba) because of some struggle that happened years ago.

Setting aside the reasons why it was implemented in the first place, it has persisted largely because there is a sizable Cuban American population in the third most populous state, Florida.  Which, it should also be noted, is also the perennial swing state with the most electoral votes.  It has long been a dangerous move to risk alienating the anti Castro voters in S Florida.  No candidate for President will do so lightly.
