Again, an article echoing Lakoff's argument, with which I agree:
Why Conservatives Can't Govern:
If leaders consistently depart in disastrous ways from their underlying political ideology, there comes a point where one has to stop just blaming the leaders and start questioning the ideology.
The collapse of the Bush presidency, in other words, is not just due to Bush's incompetence (although his administration has been incompetent beyond belief). Nor is it a response to the president's principled lack of intellectual curiosity and pitbull refusal to admit mistakes (although those character flaws are certainly real enough). And the orgy of bribery and special-interest dispensation in Congress is not the result of Tom DeLay's ruthlessness, as impressive a bully as he was. This conservative presidency and Congress imploded, not despite their conservatism, but because of it.
That is why we have Give Up blog (also run by scientists). Check out our maps.
