Weigel details it:
For the first time, there’s an issue that could pit the GOP’s best-organized and best-funded grass-roots against other parts of the party base. Talk radio helped kill immigration legislation in 2007. Some of the Tea Party’s leaders wanted that legislation to survive. Dick Armey, the former GOP majority leader who now chairs FreedomWorks, was warning Republicans to “get off this goofiness,” stop talking about a border fence, and pass the bill.
David and Charles Koch, and other businessmen who’ve discovered politics in the Tea Party area, are far more simpatico to immigration reform than, say Rush Limbaugh or Mark Levin. In 2007, Iowa Rep. Steve King fought reform so hard that he brought a small model of a border fence to the floor of the House, to show how ready-made it could be. In 2009, King was linking arms with Dick Armey. King will be in D.C. come January. So will FreedomWorks. And for the first time, they completely disagree about how they can win the country.
Sweet. Hint: Dick and the Kochs are onto something.
