times of economic turmoil causes lots of fingerpointing and scapegoating among the populace and can often lead to experimentation with totalitarian ideology.
It seems like you're implying the latter is occurring right now in the US, though...can't we all just admit Obama isn't a tyrant, Bush wasn't, and if the Tea Party comes to power it won't be?
it is not an attack on the right or left. As someone with an interest in history, I've found that times of economic distress has lead to experimentation with extremist ideology, left or right, such as Russia in 1917 or Germany in 1933.
