In case nobody has heard, Charles Djou defeated two Democrats to pick up a congressional seat he will have to defend again in about 6 months.  He received 40% of the vote.

The last time a Republican was elected in Hawaii?  20 years ago.

Advantage:  Still the Democrats.  However, elections are about more than party ID, and Djou is pretty articulate.  He has a few months to gain the voters’ favor.
