The countdown to the US presidential elections is under way. US President <a href="https://www.thenationalnews.com/tags/joe-biden/" target="_blank">Joe Biden</a> and Republican <a href="https://www.thenationalnews.com/tags/donald-trump/" target="_blank">Donald Trump</a> have <a href="https://www.thenationalnews.com/world/us-elections/2024/03/13/biden-trump-nominations-election/" target="_blank">reached the required number of delegates</a> to be eligible for their parties' nominations ahead of election day on November 5. <i>The National </i>takes a look at the major players and important dates in this year's presidential election: <b>Joe Biden: </b>The current US President is running for re-election after winning against Mr Trump in 2020. The Democrat entered the Oval Office after a pro-Trump insurrection attempt at the US Capitol, and led the country out of the worst of the coronavirus pandemic and the accompanying economic fallout. The oldest president in US history, Mr Biden, 81, is <a href="https://www.thenationalnews.com/world/us-news/2024/02/09/biden-special-counsel-report-memory/" target="_blank">facing mounting challenges over his age and mental competency</a>, as well as backlash over his administration's <a href="https://www.thenationalnews.com/world/us-news/2023/12/19/biden-faces-widespread-disapproval-over-handling-of-israel-gaza-war/" target="_blank">handling of support to Israel during the war in Gaza</a>. <b>Donald Trump:</b> The former president, <a href="https://www.thenationalnews.com/opinion/comment/2024/05/31/donald-trump-is-a-convict-voters-will-decide-whether-it-matters/" target="_blank">now a convicted criminal</a>, is making his third bid for the White House. Trump, the leading Republican candidate, is <a href="https://www.thenationalnews.com/weekend/2023/12/29/trump-courts-2024-law/" target="_blank">facing more than 50 other charges</a> across several court cases. He has been accused of mishandling classified documents and leading a conspiracy to overturn the results of the 2020 election. Now 78 years old, he also <a href="https://www.thenationalnews.com/news/us/2024/06/14/donald-trump-turns-78-highlighting-voter-concerns-over-age-in-2024-us-election/" target="_blank">faces concerns about age from voters</a>, but the focus has been on his <a href="https://www.thenationalnews.com/news/us/2024/06/12/what-is-project-2025/" target="_blank">anti-democratic aims</a>: he has <a href="https://www.thenationalnews.com/world/us-news/2023/12/06/trump-says-he-will-not-be-dictator-except-on-day-one-if-president-again/" target="_blank">pledged to be a dictator on “day one”</a> if elected. In the Republican Party: The party originally had a crowded campaign field, although no candidate posed much of a challenge to Trump. The leading candidates against Trump were former US ambassador to the UN <a href="https://www.thenationalnews.com/world/us-news/2024/03/06/nikki-haley-republican-donald-trump/" target="_blank">Nikki Haley</a> and Florida Governor <a href="https://www.thenationalnews.com/world/us-news/2024/01/21/ron-desantis-drops-out-of-us-presidential-race-and-endorses-trump/" target="_blank">Ron DeSantis</a>, who both dropped out in early 2024. They were awarded 97 and nine delegates, respectively. Entrepreneur Vivek Ramaswamy had three delegates, although he also pulled out of the race. In the Democratic Party: Mr Biden not had no major competition throughout the campaign. The only candidates to have gained delegates is entrepreneur Jason Palmer and Minnesota Representative Dean Phillips, with three and five delegates, respectively. Author Marianne Williamson is also running, but she has not won any delegates. Mr Biden is still facing challenges in his party, with a small but vocal movement <a href="https://www.thenationalnews.com/world/us-news/2024/02/28/a-resounding-victory-in-michigan-rings-alarm-bells-for-biden-campaign/" target="_blank">encouraging Democrats to vote “uncommitted”</a> in the primaries in response to the President's support for Israel during the war in Gaza. The uncommitted vote has been awarded 36 delegates. For the Independent Party: Lawyer <a href="https://www.thenationalnews.com/world/us-news/2023/10/09/robert-f-kennedy-jr-announces-independent-2024-presidential-bid/" target="_blank">Robert F Kennedy</a>, a nephew of former president John F Kennedy, is running for office, with his campaign focused on anti-vaccine activism. Ivy League professor and academic Cornel West is also running as a progressive. For the Green Party: <a href="https://www.thenationalnews.com/world/us-news/2023/11/22/jill-stein-2024-campaign/" target="_blank">Jill Stein</a>, who ran for president in 2012 and 2016, is running for her party's nomination again. A party convention is when delegates from every US state and territory formally submit their votes to nominate a candidate to represent the party in the presidential election. Conventions often feature speeches by party leaders and the candidates. Two debates between the two major party candidates will take place this election season. Normally, the debates are held at universities after the party conventions and organised by the Commission on Presidential Debates, a bipartisan nonprofit group. However, both the Biden and Trump campaigns opted out of that long-standing tradition, citing issues they had with scheduling and with the commission. They instead <a href="https://www.thenationalnews.com/news/us/2024/05/15/make-my-day-pal-biden-challenges-trump-to-two-televised-debates/" target="_blank">co-ordinated their own debates</a> with television networks on the basis of rules and formats they agreed on – no audiences, enforcing time limits on questions, and holding them earlier because of early voting. Election day is on November 5. The US President is not elected by popular vote, but rather by a majority of electors, in a <a href="https://www.thenationalnews.com/world/joe-biden-says-democracy-prevailed-as-us-electoral-college-formalises-his-win-1.1128864" target="_blank">unique system called the Electoral College</a>. Each state has a specific number of electors based on the census, depending on the number of senators and congressional districts. A presidential candidate <a href="https://www.thenationalnews.com/world/can-both-candidates-get-to-270-votes-here-s-a-look-at-the-top-election-internet-searches-1.1106609" target="_blank">needs the support of 270 out of 538 electors</a> in the Electoral College. After the electors hold meetings in their states and send in formal certifications, members of Congress meet at the Capitol in Washington to certify the results on January 6, 2025. Inauguration day is on January 20, 2025.
