President Donald Trump is responding to a possible run by former New York City Mayor Michael Bloomberg for the Democratic presidential nomination, saying: "I know Michael. He became just a nothing. There is nobody I'd rather run against than little Michael."
Trump was responding to news that the billionaire Blomberg is opening the door to a 2020 White House bid.
Trump predicted Friday his fellow longtime New Yorker is "not going to do well" but suggested his candidacy would be most damaging to former Vice President Joe Biden, another moderate.
Trump says Bloomberg "doesn't have the magic to do well" and predicts Bloomberg will fail after spending "a lot of money."
Bloomberg initially ruled out a 2020 run and has not made a final decision on whether to jump into the race. Bloomberg warns the current field of Democratic candidates is ill equipped to defeat Trump next year.
The former mayor has not formally announced he is running, but has toyed with a national campaign in the past and is expected to register in Alabama before the close of business Friday. The southern state has an early filing deadline to participate in its presidential primary contest.
Bloomberg was a long-time Republican, but also ran as an independent. He is currently a Democrat.
Bloomberg's net worth is estimated at 52 billion dollars, while Trump's is closer to 3 billion.
At least two of the top Democratic candidates - Elizabeth Warren and Bernie Sanders - have railed against billionaires pushing for higher taxes on the ultra wealthy.
