On this morning’s edition Morning Joe, host Joe Scarborough and Arianna Huffington added more valuable insight into the rancorous battle over Chuck Hagel’s nomination as secretary of defense. In particular, both asserted confidently that Bill Buckley would have backed the nomination. In response to Scarborough’s comments that “extremists have taken over the party,” Huffington asked, “And don’t you think William F. Buckley would be endorsing Chuck Hagel right now?” “Yes,” Scarborough said.
