The biggest obstacle in politics is the lack of information on key topics. The media can tell blatant lies and get away with it due to people being uneducated, they do it on a regular basis. Obstacle #2 is lack of restrictions on special interest lobbyist funding and lack of term limits for congress/senate. #3 the news media monopoly where a handful of corporations own more than 90% of the media has to be broken up. Or funding and support must be diverted towards bolstering independent sources of information. This is an extremely easy question to answer. The problem is everything about media today treats important issues as if they were high school drama. Real questions on real topics are never addressed and over time people have lost the capacity to do so through neglect.
