No. In fact there are no Republican strongholds in Hawaii. The State Senate is unanimously Democratic.
I just checked the Republican members of the Hawaii State Legislature come from and I discovered that The Hawaii Senate doesn't have any GOP members (ROFL 
) and there are seven Republicans in the Hawaii House of Representatives - all of whom represent places in the area in question. Do you know where the one Republican sate senator from the last legislature came from?
PS: Do you know where I can get CD-level results? I wanna calculate it myself.
The last one was Sam Slom of the 9th district, representing "Hawaiʻi Kai, ʻAina Haina, Waiʻalae-Kahala, Diamond Head", as per wikipedia.
