Never forget that so much comes down to the gamesmanship imposed by the US adoption of first pass the poll voting instead of something like instant runoff or another ranked choice voting system, where every voter, even in primaries, has to adjust their vote based on their prediction about how their neighbor is going to vote.
Unfortunately, so long as the US keeps this system of voting there will always be strategic voting that skews people's votes as they play that game.
But in the end, if we do take your conclusion that Americans are right-wing, well I guess democratic principles would say we deserve to have right wing politicians representing the country. If you really want to go that direction.
