Nobody, actually. Arizona is one of only a handful of US states that does not elect a lieutenant governor, as such an office is not specified in the state's constitution. The first in line to succeed the governor is the Arizona secretary of state.
There is no such position in Arizona government.
In States that have that position, it is the Lieutenant Governor.
43 states have a lieutenant-governor. 25 are elected with the governor and 18 are elected separately. Arizona, Arkansas, Maine, Mass., New Hampshire and Oregon do not have a lieutenant-governor.
The Secretary of State assumes the power of the Governor when the current Governor dies, resigns, or leaves office for other reasons. The current Secretary of State in Arizona is Jan Brewer, a Republican. The current Governor of Arizona is Janet Napolitano, a Democrat, who is currently being considered to become part of President-Elect Obama's cabinet.
That would be the "Lieutenant Governor".
The current Lieutenant Governor of Ohio is Mary Taylor. Taylor assumed office as Lieutenant Governor of Ohio on January 10, 2011.

People do not vote for a Lieutenant Governor. He or she is selected by the candidate running for Governor.
State voters elect the lieutenant governor. In most states, the governor and lieutenant governor are elected together on a single ticket, but other states vote for lieutenant governor separately, meaning he or she may be from a different party than the governor.
