Bruce Dixon on why Obama makes Republicans even crazier. Go read it all:
Three things happen when a corporate right wing Democrat steals Republican positions.
The first is that because of the two-party duopoly, when a Democrat moves rightward, his constituents have nowhere else to go. Democrats and Republicans have cooperated, in most of the fifty states, to throw up massive barriers to ballot access for third parties, and by requiring big money to access broadcast and cable networks, the corporations who fund both parties limit public discussion to what their corporate funded politicians are saying.
Freed from the need to represent the have-nots, who must now vote for him no matter what he does, or an even worse Republican, the right-leaning Democratic president can now claim he is looking for “the center,” or to pick up Republican-leaning voters. In the Clinton era, these sought-after voters were called “Reagan Democrats,” and Clinton got a lot of them in 1996.
The second thing that happens when corporate Democrats steal the policies of Republicans, is that since they nominally represent the have-nots, who now have nowhere else to go, they are often more effective at imposing Republican policies upon the polity.
