Presumably, a lot of people will be interested in running for lieutenant governor if Huckabee calls an election. Russ didn't rule out the possibility that he might be one of them, even though he believes a special election is unconstitutional. The Constitution apparently would prevent him from running for the lieutenant governor's job while he's a senator, or resigning his Senate seat to run for another state office, but the date of the special election could be important. Russ' Senate term will expire at the end of the year. He's seeking another term, and is unopposed in the general election as he was in the Democratic primary.
Answers remain cloudy.
