not voting just means that someone wins with a smaller amount of votes. the UK recently had their elections, the winners only had 34% of the populations vote, so 65% of people didn't want them, yet they still won. if you don't like Trump or Harris, you are better off voting for a 3 rd party that wasting your vote totally.
the only way to chhange that is to have 'none of the above' as an option, that way everyone can see that those selected are not wanted, maybe then a change of candidate can be done, but it doesn't seem the there is a choice regardless in the US, quite ironic seeing as the US invades other countries in the name of 'democracy' but don't have or accept it their own.
