A resident fascist ideologue at BNet asks, "How are the Koch Brothers any different from George Soros?"
George Soros doesn't control any state legislatures.
The American Legislative Exchange Council (ALEC), a front group for the Koch brothers, major corporations, and right-wing lobbying groups, all elements of the hidden fascist rule of the fascist USA, controls the legislatures in most of the states with Republican majorities.
If George Soros had anything comparable to the Koch brothers' power, the US would not be the fascist nation/empire it has become. Contending and/or pretending he does is ludicrous, a game played by fascist ideologues or repeated by their gullible and credulous dupes.
