Takes 5 minutes of skimming campaign sites and the first page of google results,
tops, to pick the least-horrible candidate among the (if you're lucky) two viable ones for a given election at the state or national level in the US, assuming you haven't picked up enough by cultural osmosis to make the decision with no further effort.
Local elections are a different matter, but closely following state and national policy and politics is a fairly useless hobby (so it's fine to do so if you enjoy it!) for most people, unless they plan to get much more seriously involved in the process than voting and maybe stuffing envelopes for someone. Or if they have some kind of need for deep knowledge of that stuff for business reasons, I guess, but few have such a need.
