Last night I caught an interesting moment on the Keith Olbermann show: they were alarmed at the continuing breakup of the Republican party. Don't cheer it, they warned. This is a moment that could bring forth a new independent party that could wreak havoc (i.e., hurt Obama) in the 2012 elections. Palin? asked Keith in a shaky voice. No, something far worse, someone from outside the political system, a "demagogue" combining Ross Perot's attacks on federal spending and deficits and "Pat Buchanan's nativism," who would rally angry people against the regime.
