I'm posting this topic in the Agnosticism section because i consider independents to be the agnostics of politics. I think some of the same reasons that independents leave the Republican and Democrat parties is similar to the reasons why agnostics leave Christianity or atheism.

I'm an independent myself, and I just got tired of the Democrat and Republican party. They oftentimes became too extreme and polarizing for me (just as atheists and Christians became). There might be other reasons so I invite all independents to share why they became an independent.

I'll also look for information on other sites or go into more detail about my experience.
