With two parties divided along ideological left-right lines, it’s expected that a majority won’t be switching side too often in their lifetime. The opposite would be ideologically weak parties doing a form of clientelism that would change according to the trends of the day.

Comparing the US system with parliamentary governments - I reject the assumption that the two parties are clearly divided along left-right lines. People all have a pretty wide diversity of opinions there are plenty of people I know that are both pro-life and pro-medicare for all - they don't have a home in the US political system and thus have to settle for one party of the other.

The US's two-party entrenchment forces this false appearance of an us vs. them political battle. It's true that in the US you can only legitimately vote for either D or R in races and that this further entrenches the two parties - but issue voters should be flowing pretty freely between the two parties as their individual focuses shift.

Like the Southern Strategy, the Blue Dog Democrats, Tea Party, and Donald Trump (party-switcher).

Look at the radical positions calling themselves "conservative" today, getting more extreme since the 1980s when religous extremists stated taking over the Republican Party.

One-third of US voters are Independent not registered to a party.

The US electoral system forces to parties, but those parties change and are sometimes replaced.
