A lot has changed for Pete Buttigieg, the Democratic mayor of South Bend, Indiana, in the few weeks since he’s hit the campaign trail for president.

Buttigieg, a dark horse contender with an energized base of supporters, told CNN’s “New Day” on Tuesday that he’s seen his 2020 efforts go from being viewed as “adorable” to “plausible” in less than two months.

Asked what he views as his greatest weakness, Buttigieg said it was his visibility.

“Up until now, I thought it was that nobody knew who I was or could say my name. I think that’s started to change,” he said. “Look, I’m still very different from what most people picture when they picture a president ― that’s part of the idea that we need something different.”

The Navy veteran continued: “As somebody who was sent to war on the orders of a president, I know just how much trust we put in that office. And there are very good reasons why we really hold all of our candidates to a high bar. ... And I think I’ve gone from being viewed as, you know, adorable six weeks ago to now plausible.”
