BTW: Indie voters typically strongly align on one or other side of the partisan divide despite their self-assigned labels. The nature of the two-party system is it binarizes the entire discourse and ends up reproducing the bipartisan dynamics by restricting and chopping up the Overton window according to the two major lines of thought. For more true independence you'll need proportional representation and multiple parties. The problem would (does) still exist but across a wider spectrum of opinion.
The two major parties share the partisan vote.
This means Republicans are actually a quarter of us along with Dems.
Party line voting is not the only game in town. Roughly half the nation wants to vote FOR something, not AGAINST "the bad guys"
