Arguably, yes. Or at least USA are lacking in universal suffrage while they don’t allow long time residents to vote because they lack citizenship.
This is actually a fault in quite a lot of western democracies but USA is actually worse at this the the average democracy. Contrary to most European democracies, foreign citizens are not even allowed to vote in primaries or local elections in the USA.
Off course USA has more problems with how they grant voting rights the just the lack of rights to vote for foreigners, this includes prisoners in many states, but also access to voting and voting registration, as well as disproportionate representation from election outcomes which reflects actual ballot counts poorly. All of this adds to make the USA a rather lacking in democracy.
