The Daily Beast's Howard Kutz points out the power of the Tea Party to ensure that Republican candidates toe the party line:
If you assembled a Republican primary candidate in a laboratory, it would be hard to build a more breathtakingly conservative specimen than Rick Perry.
Social Security is unconstitutional? Check. Evolution is suspect? Check. Being gay is a choice, like being an alcoholic? Check.
But wait—bzzt! There’s one malfunction here. Perry opposes illegal immigration, to be sure, but believes the children of such immigrants—often brought here at a young age—ought to get in-state tuition breaks so they can go to college and not be a burden on society.
And with that, he has flunked the Purity Test.
It is a test being imposed on everyone who wants the GOP nomination, and it has never been more stringent or located farther to the right—a sign of the stranglehold the Tea Party has on the process.
Never mind that a position was perfectly acceptable for a Republican in 2008; if it fails the Purity Test now, it must be explained away, preferably with an apology. George W. Bush and John McCain would be laughed off the stage these days for the positions they took on immigration.
