With a little under a month to go before January’s Iowa caucuses, former South Carolina Gov. Nikki Haley’s campaign is seeking to capitalize on the momentum her presidential bid has gained in recent months The New York Times reported Monday.

She hopes to reach persuadable voters in the state as the main alternative to former President Donald Trump for the Republican nomination,.

Haley received a vital boost last month with the endorsement of Americans for Prosperity Action, whose backing has infused her campaign with funds for television spots and mail advertisements.

In addition, the super PAC founded by the billionaire industrialist brothers Charles and David Koch has a goal to knock on 100,000 doors before the caucuses, said Drew Klein, a senior adviser with AFP Action.
