Powerline: the Obama administration's attack on the constitution, part 1: Immigration. "It is hard to imagine anything more flagrantly unconstitutional than Obama’s planned issuance of millions of work permits to illegal aliens who are prohibited from employment by the federal statutes." And part 2: Environmental Protection Agency. "What the EPA is doing, in attempting to refashion the nation’s electric power production system with no authorization from Congress, is both illegal and unconstitutional." And finally, White House exempts itself from Freedom of Information Act. That last link is to BoingBoing, hardly a bastion of anti-liberalism.
