This is a bit of a trick question! Maine's coastline is famously long and jagged, but that's because it has many inlets, bays, and islands. If you were to stretch out Maine's coastline, smoothing out all those inlets and bays, it would be significantly shorter.

Therefore, many states would have a "smaller" coastline than Maine when stretched out, including:

* Florida: Florida's coastline is longer than Maine's when measured using the standard method (including all the inlets and bays). But if we stretch it out, Maine's would likely be shorter.

* California: Similar to Florida, California's coastline is longer in its natural state, but would likely be shorter when stretched out.

* Texas: Texas has a long coastline, but it is relatively straight compared to Maine's.

It's important to note: This is a hypothetical scenario. It's impossible to know exactly how long each state's coastline would be if it were stretched out.
