There will be a time in the future when most Congressional Republicans will once again do more than pay lip service to conservative principles of fiscal responsibility and small government. They will start to viciously defend the Separation of Powers, question every warrantless wiretap and every executive violation of habeas corpus. They'll look for--and point out to everyone--every instance of cronyism and incompetence at all levels of government. They'll rage against every use of a Presidential signing statement, and they'll scream "impeachment" every time the President so much as sticks a toe outside his Constitutionally defined authorities.
Unfortunately, that time will be right after the next Democrat President finishes his Oath of Office.
