Overall observation
Alternating administrations: Since 1945, Democrats and Republicans have alternated in office, especially between key presidential terms, such as between Truman and Eisenhower, between Kennedy and Nixon, etc.
Continuous rule: Sometimes a party stays in power for multiple terms, for example, the Democrats stayed in power from 1961 to 1969 (Kennedy and Johnson) and from 2009 to 2017 (Obama).
Republican Dominance: Between 1981 and 1993 (Reagan and Bush Sr.), the Republicans won two consecutive presidencies.
Recent Trends: After Trump was elected in the 2016 election, the Democrats regained the presidency in 2020 (Biden).
in conclusion
Overall, there has been a clear trend of alternation and competition between the Democratic Party and the Republican Party for the presidency since 1945. With Trump and Musk's continued support, it seems that he has a sure win.
