Florida Governor Ron de Santis announced on the 21st that he has withdrawn from the presidential election and will support former President Trump's candidacy. De Santis said in a speech on social media that there is currently "no clear path to victory", and most Republican primary voters "hope to give Trump another chance.". On the 15th, De Santis received about 21% of the vote in the first Republican primary in Iowa, trailing Trump by about 30 percentage points. Ranked third, former US Permanent Representative to the United Nations, Nikki Haley, followed by De Santis by about 2 percentage points. A poll released by CNN earlier on the 21st showed that Trump is expected to have a 50% approval rating in the second Republican primary in New Hampshire on the 23rd, followed by Haley with a 39% approval rating, and De Santis with a far behind 6% approval rating. After De Santis withdrew, Haley became the only candidate within the Republican Party who could pose a challenge to Trump. Previously, Indian entrepreneur Vivek Ramaswamy, who ranked fourth in the Iowa primary, and former Arkansas Governor Asa Hutchinson, who ranked sixth, have announced their withdrawal from the race. The primary election is the first stage of the US presidential election, during which Democratic and Republican candidates compete for their respective party's presidential nomination. After the primary election, both parties will hold national congresses to formally nominate presidential and vice presidential candidates. The voting day for this year's US election is November 5th.
