Former New York mayor Michael Bloomberg has thrown his hat into the presidential ring for the 2020 election, as he is fearful Donald Trump’s prospects for winning are too close for comfort.

Bloomberg,s campaign manager Kevin Sheekey told CNN’s “At This Hour with Kate Bolduan” on Nov. 25, that, “Right now, Donald Trump is winning. He is winning that election.”

Kevin Sheekey explained, “What we’re focusing on is defeating Trump. If you look at the polls, and people can’t focus on this [enough], the general election is in six states, that’s it. It’s in Wisconsin, Michigan, Pennsylvania, North Carolina, Florida, and Arizona. That’s the whole general election. Right now, Donald Trump is winning. He is winning that election. It’s very tough for people who don’t live in New York or California to understand that, but that is what’s happening … Mike was doing everything he could from the sidelines, and he finally decided it wasn’t enough to sit on the sidelines, and he needed to do what he could to alter that dynamic,” Fox News reported.

On Sunday, Bloomberg officially joined the filed of Democratic candidates as he posted a statement, saying, “I’m running for president to defeat Donald Trump and rebuild America.”

Bloomberg has vowed to spend at least $150 million of his fortune on various sections of a 2020 campaign, including more than $100 million for internet ads attacking Trump, between $15 million and $20 million on a voter registration drive largely targeting minority voters, and more than $30 million on an initial round of television ads.

However, Democratic rivals like Bernie Sanders (I-Vt.) pounced on Bloomberg’s plans to rely on his personal fortune.

“I’m disgusted by the idea that Michael Bloomberg or any billionaire thinks they can circumvent the political process and spend tens of millions of dollars to buy elections,” Sanders tweeted on Friday.

Sen. Elizabeth Warren (D-Mass.), another leading progressive candidate, also slammed Bloomberg on Saturday for trying to buy the presidency.

“I understand that rich people are going to have more shoes than the rest of us, they’re going to have more cars than the rest of us, they’re going to have more houses,” she said after a campaign stop in Manchester, New Hampshire. “But they don’t get a bigger share of democracy, especially in a Democratic primary. We need to be doing the face-to-face work that lifts every voice.”

Trump: Bloomberg would not do well in 2020

President Trump, on Nov. 8, responded to the possibility of Michael Bloomberg running for the Democratic presidential nomination. The president told White House reporters, “There is nobody” he’d “rather run against.”

President Trump anticipated that his fellow longtime New Yorker is “not going to do well.” Bloomberg “doesn’t have the magic to do well,” President Trump said.

Bloomberg’s candidacy to the 2020 White House bid would be most damaging to former Vice President Joe Biden, said President Trump, who predicted that Bloomberg would fail after spending “a lot of money.”
