The Tea Party is actually well-informed, but none of their information is accurate or truthful, so I would say that they are the least informed.
Independents generally have to sort through a lot of bullshit from both sides, and are capable of critical thinking as opposed to merely parroting the party line, so I would argue that they are the most informed.
The Republicrats and Democrans are generally so polarized that it has warped their brains to where they can’t even comprehend alternative viewpoints, so it’s safe to say that neither of those parties is well informed, and that any person who claims to be affiliated with either of them is either half-blind or is actually an Independent
As for “Other”, there are almost as many political parties as there are religions, and some of them are too small for anybody who knows anything about statistics to make any meaningful statements about the party as a whole (too small a sample size to adjust for anomalies) so that category is out unless you want to group them with the Independents.
@Discobitch Most of my shipmates were more liberal than I am, as were many of the Marines I served with. Of course, the other branches all derisively refer to the Army as where people who want to serve but don’t have the intelligence to be Navy or Air Force, or the balls to be a Marine wind up. Half-witted cowards…. sounds like a Republican to me!
