(CNN) Colorado Republican Senate nominee Ken Buck and his former challenger, Jane Norton, teamed up Wednesday, in the first joint-appearance by the two since the state's August 10 primary.
Norton, a former lieutenant governor, formally endorsed Buck at an event in suburban Denver.
"This is a really important election and we have an opportunity to take the Senate back. Ken is an extraordinary campaigner. He is going to go to Washington, he is going to vote to take our country back and to get us on sound financial footing. So I'm here to say, 'please support Ken.' I am doing it, and I hope all of you will," said Norton at the unity event, according to a press release from the Buck campaign.
Buck, the Weld County district attorney, was once a long shot in the battle for the GOP nomination, but thanks in part to support from some in the Tea Party movement, he defeated Norton, who was recruited to run by national Republicans and was the early favorite in the race. While the primary battle turned negative on the airwaves in the weeks leading up to the election, Norton did endorse Buck in her concession speech.
"I said on primary night that we had a little dust up in the family, and the family is now coming together, and I really appreciate what Jane has done for us," said Buck.
Buck now faces off in November against Democratic Sen. Michael Bennet, who survived a spirited primary challenge from former Colorado House Speaker Andrew Romanoff. Bennet and Romanoff teamed up with Democratic National Committee Chairman Tim Kaine at a unity rally on the steps of the state capitol in Denver two days after the primary.
"Democrats came together immediately following the primary last month. We are unified to turn out all our supporters in November for the Democratic ticket. It says a lot about the disharmony in the Republican party that it took Norton almost a month to have a public appearance with Ken Buck and at such a small venue," said Colorado Democratic Party Chair Pat Waak, in a statement to CNN.
The most recent polls of likely Colorado voters suggest Buck leads Bennett by single digits.
