Final answer:
Ties are more likely in the Senate due to its smaller size and the broader representation senators must provide for their entire state, leading to a higher probability of evenly split votes. The Vice President breaks ties, a role that became critical after the 2020 election's 50-50 Senate split.
Step-by-step explanation:
Ties are far more likely to happen in the Senate than in the House of Representatives due to the smaller size of the Senate. Compared to the House's 435 members, the Senate has only 100 members, which increases the probability of a tie occurring. Additionally, senators must represent the broader interests of their entire state, as opposed to House members who represent smaller, more homogenous districts. This can often lead to more bipartisan cooperation and a greater likelihood of evenly split votes within the Senate. The Vice President of the United States presides over the Senate and has the power to cast a tie-breaking vote. This provision is essential in a chamber where ties are more conceivable, especially during situations like the 2020 election, which resulted in a 50-50 split, effectively making the Vice President's vote crucial in passing legislation or making decisions.
