Glenn "Instapundit" Reynolds and his wife Dr. Helen lured Rudy Giuliani into their podcasting lair for an extended conversation this weekend. Rudy offered a warm embrace of the 2nd Amendment, but didn't seem totally up to speed on flex-fuel vehicles. ("Up to speed." Get it? Ha!) Sadly, Rudy didn't sound sincerely enthusiastic about Dr. Helen's idea for tax credits for podcasts.
