Any alcohol will absorb water, even the moisture out of the air, but if allowed to sit will probably separate with the fuel floating on top. Ethanol gets a bit of a bad rap really. The positives are that it will readily absorb into the gasoline with a little agitation, it raises the octane ratings a bit (alcohol is slower burning) and it cleans the fuel system very well, removing varnish and water,, to a point.
The bad is that it absorbs water out of the air and at some point the water content becomes excessive causing “run” issues. Also it has fewer btu’s of energy per volume compared to gasoline so it’s less efficient, less power & less mpg’s unless tuned for it, (more compression & timing)
And finally, because it absorbs water in my opinion unscrupulous station owners can add water to their tanks w/o causing any real problems, boosting their profits by adding the water , this is just my opinion though, but I have seen it done years ago and it left an impression of how bad some can be. The ethanol helps cover that practice and really Make it not as noticeable.
Finally, if it were me, i’d Drain the tank as some have suggested and refill with fresh gas and i’d Also add some new spark plugs along with the wire refresh suggested by Ray earlier.
