Why do you think the requirements fot serving in the senate are stricter than those for serving in the house or representatives?

There are fewer members of Congress in the Senate as each state only gets exactly 2 senators while the house of reps is based on population and currently has 435 members. this makes the Senate more powerful and harder to get into.
senate terms are also 6 years while house of reps terms are only 2 years. these are only a number of factors making the senate more desirable to be in for someone seeking a position of power, leading to stricter regulation for candidates to win a seat in the senate
