Maximum Value For Your Prosecution Dollar
Simply put, the PEQ is the amount of money spent on investigations to date divided by a politician's TIT. The ideal PEQ is one, of course, and when reached you can be assured that the prosecutor has worked the politician's TITs as much as possible. However, if the PEQ is over one, then the TIT is exhausted and investigations must stop.
So how do some recent prosecutions stack up? Well Bu$hCo's TIT from the 2000 election is $18.5M and the Plame-gate investigation has only spent $800K so far, yielding a PEQ of .043. This is frankly lousy, but when you consider that we already have one indictment with more to come it could be considered a measure of Patrick Fitzgerald's efficiency. At this rate the investigation could easily continue for the remaining 3 years of the current administration.
Ken Starr, on the other hand, spent $40M plus on his investigation, but Clinton's TIT (derived from the 1996 campaign) was only $3.8M. This yields a whopping PEQ value of 10.2. In other words, Ken Starr exceeded the Clinton TIT by $36M, and wasn't even able to secure an impeachment. For that much money, Starr should have been able to secure impeachments of every official in the Clinton White House!
