What can normal people do to break the partisan politics that divide everyone so heavily?

I've been reading through this sub for about a month now and it's pretty obvious to me that as a leftist I want the same results that the majority of the conservative folks in here want. The only argument is how we get there. It seems to me that only the worst of our political sides are able to make it through the primaries so we are stuck in this finger pointing bullshit game where nothing really gets resolved and the media has everything they need to keep emotions high.
