I agree there are people who don't care about politics much, some who are utterly obsessed with the details, and some who care about it when there are elections.
I'm some combination of the last 2 categories. I care about politics, but (other than here) I don't worry about it too much. I just want to keep track of what the political fanatics are saying about once a week.
When election time comes along, I ignore what the candidates are saying then and look at what they have done before. I look at what they have done and supported in the past. What they have done before is the best guide to what they will do in the future.
I don't listen to campaign speeches, I don't listen to what their surrogates say on talk shows, I don't listen to what they say in a campaign. I just look at what they have supported and done before.
That's all I need to know and all anyone needs to know.
