Is a senator higher than a governor?

These positions are not really comparable -- they serve different purposes and are not in the same chain of command. In my state, the governor can not serve consecutive terms but there are no restrictions of the state senators. So, some few state senators become very powerful - more powerful than the governors. Other senators have little power . As for US Senators, some become very powerful- more powerful than any state governor. On the state level, US senators are often influential in the state and may virtually hand-pick the candidates for governor.
