2005 Federal Sentencing Guidelines
Chapter 2 - PART E - OFFENSES INVOLVING CRIMINAL ENTERPRISES AND RACKETEERING
§2E1.2. Interstate or Foreign Travel or Transportation in Aid of
a Racketeering Enterprise 
(a) Base Offense Level (Apply the greater):
  (1) 6; or
  (2) the offense level applicable to the underlying crime of violence or
    other unlawful activity in respect to which the travel or transportation
    was undertaken.
Commentary
Statutory Provision: 18 U.S.C. § 1952.
Application Notes: 
1. Where there is more than one underlying offense, treat each underlying
  offense as if contained in a separate count of conviction for the purposes
  of subsection (a)(2). To determine whether subsection (a)(1) or (a)(2) results
  in the greater offense level, apply Chapter Three, Parts A, B, C, and D to
  both (a)(1) and (a)(2). Use whichever subsection results in the greater offense
  level.
2. If the underlying conduct violates state law, the offense level corresponding
  to the most analogous federal offense is to be used. 
3. If the offense level for the underlying conduct is less than the alternative
  minimum base offense level specified (i.e.,
  6), the alternative minimum base offense level is to be used.
