Confirmation bias is one of the strongest forces for shaping the way we think and creates some pretty huge distortions between what our brain thinks is reality and actual reality
You can't pay attention to everything in a newscast but what you do pay attention to says a lot about your bias and what you want your viewers to think
If your side or candidate does something bad, ignore it. If that doesn't work then interpret in the most generous way possible then refocus on how bad the other side is
Whatever the other side does make sure you interpret it in the worst way possible
