　　While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.As can be seen from the new data, female bodyguard The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. http://huanyubodyguard.com/

　

　　

　　The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

　　

　　The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

　　

　　As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.
