We often think good or bad, right or wrong. When it comes to Presidents, those are the wrong categories to use. Trump to Biden was bad to worse or perhaps worse to bad, but there seems no way to pick one or the other as 'good.'
Most of us choose between candidates based on 'what's the worst they can do.' And then after the election, the political machine propels people into thinking one candidate is good by having a big celebration like a big football victory.
But we know it's a lie. Everyone knew Joe Biden was senile or very nearly; we hoped he wouldn't do much harm. We were hoping for zero. We didn't get it.
Starting our thinking with two-party politics results in a severe amount of 'dumbing down.' Because we know in the end we need to choose between two parties, we start with that choice and ignore most of the options. In 2020 the DNC stated the aim was not to choose the best candidate but just to beat Trump, implicitly acknowledging they would not provide a good option.
Two-party thinking means when a President decides to do something unlikely to work out well, his own party will usually go along with it. Instead of agreeing it is wrong, the Red or Blue President gets almost 50% support from his own party, justified by some of the lamest excuses imaginable.
Red vs. Blue produces tribal thinking; them vs. us. Tribal thinking prevents about half of the voting population from thinking too deeply about issues. And that leaves the other half unmotivated because the public is just going to believe the media. And the 'Defense Industry' always wants war, so the media calls for war. So what's the point in spending time on politics when the country just goes to go to war anyway, every time?
