Yes . Parties tend to have a lot of wings that both overlap and oppose each other . In case of Progressives , it is sadly also their biggest weakness the lack of central body able to pull the ideology into a working party . If the polling claims I ' ve heard are anywhere near true , a real progressive party could sweep the US political landscape with ease , given a real chance . I actually believe one of the main reasons the Republican party still exists is that no matter how badly the party splits , they apparently always fall in line when it ' s election time . This election should stand as a testament to that Trump shot down every other major candidate they had and caused what Democratleaning news described as civil war in the party . Yet after all the big talk about hating Trump and grand standing and claiming moral high ground by opposing him , the Republican party came together to vote for their candidate .
