  • Check out the scaling on the taxes versus the cost of gas beneath. Also consider the fact that they lump state along with state and local. Strange.

  • Someone today accused me of using only “conservative graphs.” Well, here’s a liberal graph that is pretty bad, because a president who had already increased the debt by a large margin would typically lead to a new president who increased it by less (though still keeping it high). In other words, the data is dependent on the previous year. So, comparing Bush’s 115% to Reagan’s is a joke, as is the comparison of Obama and Clinton.
