Both the U.S. Constitution and the Texas Constitution name the second-in-line executive official (vice president and lieutenant governor, respectively) to chair the senate. Why does the Texas lieutenant governor have more power in this role than the vice president does today?

A. Historically, lieutenant governors have assumed a more active role in the Senate than their vice presidential counterparts.
B. The Texas Constitution provides more specific powers to the lieutenant governor than the U.S. Constitution does to the vice president.
C. The U.S. Constitution provides more restrictive powers to the vice president than the Texas Constitution does to the lieutenant governor.
D. The Texas Senate has significantly fewer members than the U.S. Senate.
