Discussions at work with college-age interns is a terrific test of just how old you’ve gotten. When I began to discuss this week my golden days on campus as a polemicist, writing an editorial in the college newspaper in support of Reagan interior secretary James Watt, I got the James WHO? look. The Washington Post today has another funny moment (can’t locate the link). The RNC has two young ladies interview prominent GOPers in an e-mail feature called “Off the Record.” In the latest edition, Sen. John Thune discusses his affinity for Styx, Boston, Journey and the Doobie Brothers — music we fogeys grew up with — but the ladies in their e-mail refer to Thune’s enthusiasm for “The Sticks.”
