Not much political stuff on the past day right now but if you look at the past month's posts about the US presidential candidates you'll see what I'm talking about.
It seems to me that your current election is a bit of a special entity, so this data might be a bit skewed. I don't know a single conservative/right/center minded person who would support the current repuplican nominee if she/he could. I think this comes from the fact that he is a very unique candidate. Saying that anti Trump is anti right doesn't acknoledge this.
There are also more general issues. Most public political discussions are not so much political but mostly ideological aka not meaningful. People who follow ideologies are self imposing an anti discussion barrier. Your two party system enforces this.
If I want political discussion and/or information then I talk to friends or read/share interesting long form articles. Democracy is complex and full of kompromises aka hard, so "quick and dirty" just doesn't cut it.
Ah, but you do, unfortunately, in the same way that non-drinking drivers have skin in the game of DUI laws and enforcement.
Going by the coverage of the refugee crisis (more relevant to me in Austria) a while back it was looking the other way around, and I mostly stopped bothering with political subs.
