    We should all use isidewith.com before each vote. After taking a quiz about where you stand on the issues, it gives a percentage match ranking with candidates. I use it to skip the horse and pony show and get to the point. Source: over 3 years ago

  • I ran a "political leanings" poll on both r/lordoftherings and r/polls and this is what I found (details in comment)
    Totally agree. In reality, there are a ton of more nuanced spectrums that are more relevant (isidewith.com). Source: over 3 years ago
