Listening to the morning radio I made an interesting discovery: A feature about speeches given by Barack Obamas throughout his presidency. What I found particularly striking was the analysis into the tone of his speeches on gun legislation. It was pointed out that over time – as he had to comfort families of gun violence time and again – the level of hope faded and a certain amout of fatigue and resignation became apparent. I had to agree with this from my own listening experience but interestingly this can also be objectified, as discussed here. (German audio).
