The presidential campaign announcements may not be over yet—with the latest potentially coming from a person who’d ruled out a run just a few months ago.

Democratic presidential candidate Michael Bennet said Sunday that Donald Trump will not be able to coast to re-election on the strength of the U.S. economy alone, and will have to answer for his “war with American tradition” while in office.

“I don’t think it’s been much better, Dana. I think it's been what it was: It’s been fine, it’s been good,” the Colorado senator said of the economy during an interview with Dana Perino on “Fox News Sunday.”

“So it has improved, just as it’s improved from 2009 when Barack Obama took over,” Bennet continued. “What we don't need — in my view, I think — is a president who’s so at war with American tradition.

“We don't need a president who doesn’t believe in the rule of law. We don't need a president who doesn't believe in freedom of the press. We don't need a president who doesn't believe in the independence of the judiciary. We don't need a president who believes he’s above the law, that he can do by executive order what Congress doesn’t do.”
