If Fred throw in his hat I will volunteer to help, RFR!!!
On another FDT thread earlier today, it was claimed he may announce late this month or in June. Apparently his contract for Law & Order is up after the last season episode on May 18th (? exact date), and he then has an HBO appearance in a film around the 29th. Once these are over he'll be clear to announce without the laws governing 'equal time' applying.
I downloaded his interview with Don & Roma here on Chicago's WLS Talk Radio, off of one of our FR threads. Great interview, showing his sense of humor. When Don introduced him as an movie and television actor, former attorney, and U S Senator, Fred responded with "what you're saying is I can't hold a job".
