(CNN) – Senator-elect Cory Gardner defeated incumbent Sen. Mark Udall, D-Colorado, Tuesday, a victory that helped the GOP clinch control of the U.S. Senate.
Udall's campaign was criticized for being too focused on women's reproductive rights.
"The senator made a mistake of not addressing more issues in his campaign," Gardner said of his opponent.
"We spent a lot of time talking to voters about a lot of issues. We ran a TV commercial saying that our campaign, this campaign should aim higher. We talked about growing our economy. We talked about energy, and we talked about the environment, and education," said Gardner.
The Colorado Republican also said once he gets to Washington, he will support Sen. Mitch McConnell, R-Kentucky, for majority leader.
