Yes, we have a disenfranchisement problem in the US. Between voter rolls being purged, people losing their right to vote due to felonies, gerrymandering out the ass, voter ID and other such nonsense trying to stop legal votes, and purposeful locking down/ limiting of voting places, it's honestly impressive so many were still able to vote. Doesn't change that what you said was wrong.
And it's 188 million, unless you think a vote for Harris wasn't voting against Trump.
