Why are you so sure the remaining 38% HAVE TO BE IND - they don't have to be anything.
We're talking about people who are registed to vote here - not some flake who is too lazy to get out of bed and vote. Being a NON-VOTER does not make you an IND. How do you know that 38% are not all UNREGISTERED ..?? And .. if that's true - your analysis is all wet!!
What a ridiculous example.
ok... 1% are Greens and 1% are Libertarian.
You seem to think it means registering for the Independent Party. It's not... it's just not being aligned with a party. All evidence shows 30-some percent of Americans so identify themselves.
