US media billionaire Michael Bloomberg today announced his official election for the Democratic presidential candidate.

Bloomberg, who earlier this year said he would not run for the White House, is now changing his decision because he does not think current Democratic candidates can beat President Donald Trump in the 2020 election, some people close to the US media billionaire said. These candidates include former Vice President Joe Biden, who Bloomberg believes has been lackluster and difficult to raise funds.

Billionaire Bloomberg said he would make practical choices to voters in the campaign to eliminate a president "representing the existential threat to our country and our values".

"Defeating Donald Trump and rebuilding the United States is the most urgent and important battle," he stressed. "I will do my best. I will become the executor and the problem solver, not the person who can only speak. I am willing to take part in difficult battles and win."

To start, Bloomberg spent at least $ 37 million on advertising on its campaign on television over the next two weeks. Bloomberg identified himself as an unexpected candidate, "a new option for the Democratic party".

Bloomberg, 77, will face enormous obstacles to win a Democratic nomination, starting with a complicated political bag with a series of problems related to his business. Billionaire America has made comments that downplay women and support inappropriate policies targeting blacks and Latinos.

Starting the race late, he will have to put in a lot of effort to catch up with other candidates in building national profiles and set up a large-scale campaign organization.

Bloomberg's colossal wealth, estimated at over $ 50 billion, could also become a political challenge for him. Many opponents have condemned Bloomberg because he used his personal property to dominate the race to the White House.

"I am not happy with the idea that Michael Bloomberg or any president thinks they can disrupt the political process and spend tens of millions of dollars to gain an election advantage," said Bernie Sanders, a Vermont senator, Democratic presidential candidate, November 22 wrote on Twitter.

The support team at Bloomberg asserts that the wealth he owns helps the US billionaire respond faster to people's concerns because he has no special interests.

Bloomberg currently primarily introduces himself as a business manager and former New York mayor. Advisers admit he is less popular with voters than other Democratic candidates.

The ad for the Bloomberg campaign emphasizes that he is a self-made billionaire rising from the middle class. He is concerned with issues such as gun control, climate change, economic development and public health.

Howard Wolfson, the chief adviser of Bloomberg, said that the US billionaire will not receive political funding when running for election and only receive a symbolic salary of 1 USD / year if he becomes president.
