Why do voters have only two choices for most political offices on Election Day?

Voters often have only two choices for most political offices due to the dominance of a two-party system, primarily seen in the United States. This system is reinforced by electoral rules such as first-past-the-post voting, which tends to favor larger parties and makes it challenging for smaller parties or independent candidates to gain traction. Additionally, the historical development of political parties has solidified the bipartisan landscape, leading to a lack of viable alternatives on Election Day. Consequently, many voters feel compelled to choose between the two major parties, even if they may not fully align with either.
