Just make sure not to take it too far if you do proportional voting. We have a system in the Netherlands that works like that but the result is that we now also have about 30 parties running for government, most of them being fairly pointless. Don’t get me wrong, it’s better than the US shenanigans but you can also go too far.
People who voted for Trump lack the ability of foresight and can’t be concerned until it directly affects them. Otherwise they don’t care and will probably cheer as their neighbors get deported.
