Wow, thanks. I like you doubt that 165,000,000 Americans are registered as Republicans. Yet, for a little different deductive reasoning and logic than yours.
...so you really are a math expert. Who knew?
So, to clarify, ALL U.S. citizens are registered voters, and nobody is Libertarian, nor independent, nor Angela Davis/Herbert-Marcusian-VladLenin party of the USA, nor Ralph Nader Green Pea Soup party?
No age restrictions like needing to be 18 to vote, nor loss of voting rights through Conviction of felonies, nor dual-citizenship?
Your first assumption is that the entire U.S. Population are eligible to be registered to vote.
Brilliant!
