Republican state senator Brenton Awa is making a long-shot bid to unseat Democratic incumbent Jill Tokuda in Hawaii's Congressional District 2, with supporters gathering on election night hoping for an upset.

• Awa trails badly after the primary, pulling in about a fifth of the vote compared to Tokuda's roughly three-quarters.
• As a Republican in a heavily Democratic state, Awa is the clear underdog against the sitting incumbent.
• His supporters say his long local ties and personal credibility could still turn out votes in his favor.
• The race centers on Hawaii's Windward Oahu communities, where Awa has deep roots.

Outlook: Given the lopsided primary results, Tokuda remains heavily favored to keep the seat.
