Quote from Epic:
I will grant you that he in fact did have a couple valleys that took him as low as Obama's valleys, so I will concede the point.
But since this is a trading site, I will present the argument a different way. Take the Truman graph and the Obama graph and take the noise out of it through something like a 30-day moving average. You'll realize that while Truman had a couple dramatic spikes down for a month or two, his first term 30-day ma was relatively flat, fluctuating above and slightly below 50%. Obama's is a very stable curve getting lower with each passing month since the beginning of his term.
Also, we should consider whether Truman's re-election was a good thing. His second term approval curve mimics George W. Bush and bottomed out at a crazy 22% approval, 65% disapproval. And in fact if you want to get technical, Obama's approval curve looks similar to GW Bush's so far, except that Bush's was about 8-point higher.
Would like to see the graph with an overlay of the ratings for congress during Truman's time and Obama's time. I know, I should dig for it myself, but maybe since you seem to know where to look?
