Republican Gov. Chris Sununu of New Hampshire announced he will not be running for Senate in next year’s midterm elections. The highly anticipated announcement came Tuesday morning as national Republicans have continued to push Sununu to challenge Democrat Sen. Maggie Hassan. In what was expected to be one of the weaker Senate seats for Democrats to hold on to the Republican Governor ultimately decided to run for re-election.

The Hill reports:

Republicans in Washington, including National Republican Senatorial Campaign Committee Chair Rick Scott (R-Fla.), had pushed for Sununu to launch a challenge against Hassan. The GOP views the seat, which non-partisan Cook Political Report rates it as “lean Democratic,” as a potential pickup in their bid to take back the Senate.

Other potential GOP contenders include former Sen. Kelly Ayotte (R-N.H.) and New Hampshire Education Commissioner Frank Edelblut.

Another run for governor in 2022 could be a safer bet for Sununu. Cook rates the race as “solid Republican.”

However, Rep. Chris Pappas (D-N.H.), who is facing an uphill reelection bid, has been floated as a potential Democratic candidate.
