That's the point.  The contest isn't going to be close.  When was the last time we didn't know the candidate going into the convention?  I'll give you a hint- it was around the time of the McGovern-Fraser Commission.  Clinton has massive leads in Massachusetts, New York, California and New Jersey.  In fact, in the five states with the most delegates, Obama has a lead in one- his home state of Illinois.  As it stands right now, the contest won't be close, and the Florida delegates may be seated with no great uproar. 
  
Edit: These polls aren't great, but there ya go.
