Session, as promoted by the Republican governor of Texas and other right wingnut so-called patriots is, by definition un-American. Un-American is precisely what the right-wingers labeled contemporary Democrats in general and progressive liberals in particular for the last 40 years.
Elections have consequences and the elections in 2006 and 2008 sent a clear message that the unholy alliance of social conservatives, fiscal conservatives, libertarians, neocons and fundamentalist Bible thumpers had pursued a set of social and economic policies that the majority of people in this country recognized as NOT in the national interest. The response of the losers has been on the order of "we want to take our marbles and go home". Having forced ultimately distasteful policies down the throats of the majority of Americans for the last 20 years they are appalled that defeat tastes (as Jon Stewart characterized it) like a sh!t taco.
