It's simple reciprocation from game-theory perspective: when the other party lies and gains advantage, you do it too. But I feel Republicans are way more untruthful than the Democrats and simply bring down the level of discussion for everyone. And I don't know why is it, that majority of Americans are so accustomed to lying that they tolerate it from politicians. In Finland if politicians get caught with outright lyi…
I know Trump is in a world of his own, but most often the “lies” are not lies to the speaker or the speaker’s fans. For example Obama’s “if you like your plan you can keep it” regarding Obamacare. It turned out not to be 100% true. To Democrats he was well-intentioned and over-optimistic and couldn’t deliver his promise (probably due to Republican obstructionism) while Republicans had always considered that a lie. If…
And about lying, there are degrees of lying that can be established. The earth is not flat even though some believe it to be so, to state the opposite is untrue. On the other hand, sure you could say eg that Americans have obesity problem (compared to the rest of the world) or they are just normal weight as "only" 1/3 of the population is overweight. But which is a truth or a lie?
I think the problem is largely a cultural shift in politics where the issues have become secondary to the rhetorical war between the two opposite ideologies. It's not about establishing a truth in a sense than it's trying to beat the other party. Yet there is a consensus that can be established, honesty that could be had when stating facts and acknowledging their up and downsides. It's not just black and white wordplay.
Perhaps we should just get rid of the politicians, have our best scientists (preferably chosen at random from a pool of candidates) run the government and people would just vote on things that they wished to improve (immigration, job-safety, healthcare etc). All results would be evaluated afterwards and their effects measured with meticulous statistics. I know that it could be abused too, but even that would be better than what is the current situation in US government.
