High voter registration... will there be high turnout?

Maui County has reported a record number of registered voters eligible to vote in the November election.  However, the September 20 primary/first special election also had the potential for record-breaking turnout because of high registration and wound up with a record low turnout of 25.5%.  Officials have also said that statewide voter registration numbers have reached all time highs.  There is little way to know how many of these voters will turn up on or before Election Day, but Hawaii is still solid Obama according to polls.
