Morse concedes to Don Bolduc in New Hampshire GOP Senate primary

• The GOP has eyed New Hampshire's Senate race as a crucial contest in their overall efforts to win Senate control in November, Axios' Josh Kraushaar reports.

Driving the news: Bolduc's opponent Chuck Morse conceded early Wednesday morning, tweeting: "It's been a long night & we've come up short. I want to thank my supporters for all the blood, sweat & tears they poured into this team effort."

• Morse, the president of the New Hampshire Senate, was boosted by more than $4.5 million from a McConnell-aligned super PAC. The PAC ran negative ads against Bolduc last week.
• Meanwhile, Democrats spent more than $3.1 million in an attempt to boost Bolduc, as they viewed him as an easier competitor to Hassan come November.
• New Hampshire Gov. Chris Sununu (R) endorsed Morse last week, while former President Trump, who never made a formal endorsement in the race, called Bolduc a "strong guy, a tough guy" earlier this month.

What to watch: Hassan earlier in the election cycle was viewed as one of the most vulnerable Senate Democrats up for re-election, but the GOP's failure to unify around a single candidate, may have opened the door for a Hassan victory in the general election, Axios' Alayna Treene reports.
