“I think they want someone different,” she added.

Less than an hour after Klobuchar's TV appearance, Bloomberg made it official. In a statement released Sunday morning, he centered his campaign on defeating President Donald Trump in the general election while also presenting himself as an alternative to former Vice President Joe Biden.

“We cannot afford four more years of President Trump’s reckless and unethical actions. He represents an existential threat to our country and our values,” Bloomberg said.

Klobuchar has positioned herself as a moderate Democrat, competing with the likes of Biden and South Bend, Ind., Mayor Pete Buttigieg for the centrist lane and criticizing some of her top 2020 rivals for promising what she calls aspirational policies, such as "Medicare for All." Earlier this month, she swiped at Bloomberg — now competing in that centrist lane with her — for thinking he could “waltz in” and declare the rest of the field insufficient.

Still, on Sunday, Klobuchar brushed off the threat his run might pose.

“We welcome everyone to the race,” she said. “People keep coming and going. And I keep steadily going up.”
