I'd argue Joe Manchin (Democratic Senator of West Virginia) has single-handedly changed an eye-watering $3.5 trillion dollar spending bill into what appears to be a slightly less eye-watering $1.5 trillion package. The lower number (and thus lower taxes) makes it much more acceptable to a broader fraction of US society. Assuming the bill passes, it's an example of compromise working (but within negotiations of a single party).
The key thing is if one party wants to be able to pass the larger number without that pivotal vote, they need to appeal to a greater fraction of society and win more seats so they don't require that particular vote.
