Hillary Clinton won’t say if she’ll enter the race for the Democratic nomination for president, but she had no problem taking jabs at Elizabeth Warren’s plans for healthcare and taxes.

Appearing at a New York Times book event, Clinton was asked about Warren’s beefy $52 trillion Medicare for All proposal.

After calling the debate “healthy,” Clinton critiqued her potential rival, noting 90 percent of Americans have health coverage in some form.

“I believe the smarter approach is to build on what we have. A public option is something I’ve been in favor of for a very long time. I don’t believe we should be in the midst of a big disruption while we are trying to get to 100 percent coverage and deal with cost…” she told Andrew Ross Sorkin.

Clinton complimented “mixed systems” in Switzerland and Germany.

When asked if Warren’s plan “would ever get enacted,” she said, “No, I don’t. I don’t.”

Clinton responded affirmatively when asked if she would support the candidate.

“I think I know who they’re likely to be,” she said ominously and declining to elaborate.

Sorkin then asked Clinton if she supports a “wealth tax” pushed by Warren.

“I don’t know the details of it. I hear about it. I hear what it would cover. I don’t understand the mechanism that would be required. I would prefer to go with the approach I put forth when I ran,” she said, adding she’s not opposed to tax increases.

“I just don’t understand how that could work. I don’t see other examples anywhere in the world where it has actually worked over a long period of time,” Clinton said, adding a wealth tax would be “disruptive.”

Sorkin ended the session by asking whether Clinton was going to run in 2020, and she avoided answering.

First answering as though it was akin to jogging, she said, “I think I would have been a really good president. I think I could have been a very effective leader,” adding she could have brought the country together because of her experience.

Clinton ended by noting she’s traveling to promote her book — and never answered the question.
