Given the Republican devotion to large corporate interests, this is not surprising:
During the Bush administration, the Justice Department did not file a single case against a dominant firm for violating the antimonopoly law.Republicans have for years strongly preferred the interests of their corporate sponsors to actual competition. Lip service to competition? That's something both CEOs and GOPers can put the full weight of their rhetoric behind.
It's odd that Democrats understand the critical nature of competition in making markets more efficient, until you think about the fact that Republican Party is first and foremost about protecting those who are already wealthy from anything might change that. Even odder is that the GOP gets away with such a narrow electoral approach by pretending that they want everyone to have a shot at becoming wealthy, the sort of social mobility that requires countervailing power against the company store, the self-protecting monopoly, and the power that wealth has due to its ability to hire the best lawyers.
