Kamala Harris has a message for the business world and traditional Republicans during the final weeks of the campaign: that she is a "capitalist."

It's a case Harris has been building since the early September release of a small-business plan that included a new $50,000 tax credit for new small businesses as part of an overall goal of triggering 25 million new small businesses in four years.

She herself underlined the point Tuesday in a Telemundo interview where she said, in remarks her campaign immediately blasted out to reporters, "I am a capitalist. I am a pragmatic capitalist."

It's a message aimed at countering Donald Trump, who often portrays Harris as a socialist or communist. And Harris is tapping figures like Mark Cuban to represent her in recent days instead of others like Elizabeth Warren (who is focused on her reelection bid in Massachusetts).

Cuban himself offered an even more colorful version of the message in a Tuesday afternoon Yahoo Finance appearance, saying "Kamala Harris is a hardcore capitalist" as part of his overall case that she's the better candidate for business.

He said the goal of these last weeks is to show Harris as a CEO of sorts and get undecided voters "up to speed on our policies and how [she is] not an ideologue or dogmatic."

It's a message from Cuban and Harris with high stakes, as recent weeks have seen a slight polling shift in Trump's favor. Multiple polling-based models still project essentially a toss-up election, but with Trump now, instead of Harris previously, as a very slim favorite.

One of an array of closing messages

What Harris is attempting to do is cut into a traditional alliance between Republicans and the business community.

And it's a strategy that comes as some financial figures and economists have expressed deep reservations about things like Trump's tariff plans that could launch new trade wars and possible disruptions to the labor market that could result from his plan for "mass deportations."

"To recap, we suspect Trump's proposed curbs on immigration and new tariffs would be stagflationary," wrote Capital Economics in just one recent example.

The capitalist focus from Harris is part of a larger outreach to traditional Republicans who may be persuaded to leave Donald Trump.

Another GOP wing clearly in focus is national security Republicans. Many of them are especially alarmed by Trump's comments about deploying the US military on "the enemy within" and a new interview with Trump's former chief of staff who told the New York Times that Trump, in his opinion, meets the definition of a fascist.

It's a message Harris underlined Monday in a series of stops in battleground states with former GOP Congresswoman Liz Cheney. "The people who know Donald Trump best, who worked up close with him, are warning about the dangers of a second Trump term," added Ammar Moussa, Harris's director of rapid response, on a call Wednesday with reporters.

Harris is also, of course, offering closing thoughts focused on her base of support, especially women. Harris is headed Friday to Texas. It's not to try and win that red state but to put a national focus on the restrictive abortion laws there.

An open dialogue with small businesses and Wall Street

The final effort from Harris comes as she and her allies do public and private outreach to business leaders of all sizes.

Harris and her aides have been in regular dialogue with JPMorgan Chase (JPM) CEO Jamie Dimon, as Yahoo Finance previously reported. This week, the New York Times reported that Dimon privately supports Harris but won't say so publicly for fear of blowback.

Harris has also used figures like her brother-in-law Tony West to reach out to business leaders.

The chief legal officer at Uber (UBER) and a former assistant attorney general in the Department of Justice, West has been on leave since this summer to focus on the campaign. He spoke at this summer's Democratic convention and has been a key intermediary between the Harris campaign and CEOs.

Cuban added Tuesday that his own focus on the campaign trail in recent days has been to talk with small businesses, adding that he's specifically asked to engage with independents and Republicans.

Last Thursday, Cuban and Harris traveled together to the University of Wisconsin-Milwaukee for a stop at a business school where students engage in a "Shark Tank"-style competition.

He also pitches Harris in the language businesses can understand: as the CEO of her campaign.

"She's only been doing it for 13 weeks," he said Tuesday. "Think of a new CEO who just took over a company and revitalized the product."
