Sixty-three percent of Americans say a third U.S. political party is needed, up from 56% a year ago and by one percentage point the highest in Gallup's 20-year trend.
Story Highlights
Third time support has exceeded 60%, along with 2017 and 2021
Republicans primarily behind the increase, with 58% now in favor
Political independents remain group most likely to favor third party
That relies on the idea that those major parties care more about winning than the policies they are currently pushing.
I don’t know too much about the US but if winning is not too important to that party voting for someone else won’t do a thing.
Another option could be that party believes they will lose more votes than gain them with the policies of that 3th party.
