While maintaining tariffs were the wrong way to go with China for President Donald Trump, estranged former White House economic adviser Gary Cohn, a self-proclaimed Democrat, does not see someone in his party worth voting for.

"I'm leaving the door open, but at this point, I don't have any intention not to vote for the president," Cohn told CBS's "Face the Nation." 

Cohn, who left the administration acrimoniously, was effusive in his praise of the U.S. economy under Trump and dismissive of the "fangled" economic plans he hears coming from all Democratic presidential primary candidates, including Mike Bloomberg, who he serves on a economic advisory board for.

"What I do know is the economy is really strong, and the Democrats haven't really come up with an idea of how to help the economy get even stronger," Cohn told host Margaret Brennan. "So it's probably easier to talk about corporate greed, and talk about Wall Street, and talk about technology companies because they don't really have an answer for an economy that's growing 2.5% with 3.5% unemployment and 3% wage growth.

"I haven't heard their answer on that, except say 'let's tax it to death.'"

Cohn has been publicly critical of the president, resigning over his rhetoric – even though it had been framed in the media as being over economic policy differences.

"I'm very supportive of the president's economic policy," he said. "I'm very supportive of what he's done on deregulation. I haven't heard anyone who's come up with a better policy yet.

"Now, I just don't vote on the economy. I vote on a lot of the social issues as well. So, you know, in many respects, I've got to balance both sides of that equation before I figure out who I'm gonna vote for."

Cohn did break from the president on the use of tariffs to leverage a phase one trade deal with China, only the result of which should be applauded.

"I don't think we would have gotten to a different outcome," he said. "I don't think the tariffs helped us get to any different outcome."

Tariffs were not the only reason he resigned from the Trump administration, Cohn told Brennan, who asked if the tariffs have hurt the U.S.

"I think it has hurt the U.S.," Cohn maintains. "I think it's totally hurt the United States."

But, Cohn said, it was only hurting in the sense it cause the administration's economic policies to be working against each other.
