Answer: The Founders believed that legislators would be closer to the people if they were elected every two years in smaller districts. Senators, on the other hand, were initially chosen by state legislatures, and the Founders hoped that with elections every six years and stricter eligibility criteria, the Senate would serve as a voice for the nation's affluent and entrenched interests.
The Founders accurately foresaw disparities between the two chambers to some extent. The Senate is more deliberative, with rigorous regulations to stimulate discussion and decorous conduct standards akin to those of a private club. The House is a little rowdier, which gives aggressive leaders more leeway.
