Interesting theory from conservative columnist George Will, who appeared on "Fox News Sunday" to say this about the divide between insurgent and establishment Republicans:
"What else is new? They split in 1912 between President Taft and Teddy Roosevelt. They split in '64 between the Goldwater right and the Rockefellers. It's a big country, and the Republicans now have what liberals are supposed to admire, which is diversity. Except liberals don't want diversity in thought. And that's what the Republicans now have, and it makes them rather interesting."
